Il demdes a ten. 你在干嘛？Goodbye. 我觉得你。This one could be a second one could be -0.52. Number one, one divided by two, multiply by three and subtrted four. Hold on, but you need even. Even means means so old means 12135. Well, even number two divided by two, one, most seven, seven, subtract it will be three, three, four divided by two, eight, multiply by Oh no, no, no, divided by two is two and multiply by seven, 14. 14 divisubtract subtract by four, it will be ten. So subtract the even number. Subtract four, it will be even number. So multiply by seven. The even number multiply by seven also is even number so divided by two someone maybe can't do. Two. Every events it always even number. So we can test it, can't we? We can test it by using an and order it even. So let's let's use an odd number. For the first one. And an even number. Is the first answer correct? But you need first divided by two. This first one here. Any ponumber? So we're looking to see if it's even or odd, right? Yes, these two are all odd. But this this is starting with an odd number multiplying by six. And adding three, our answer is odd. Any, any whole number multiply by six, it will be an even number, but an even number, add three, it will be old. It will be old. D, so, so b, it' S B right? And here you said the answer is a. This is a right. Even number okay divide by two is one. Multiply by seven is seven. Subtract by four, subtract for. Is three. The answer there is odd, right? If I put the even if I put the even number two in, I got wrong. I got wrong. Okay. But I always think of all even our opposite that I don't know why. Okay, all right, no worries. No worries. So it's old, right? Okay, nice. All right. I'm just going to go get my my cup of coffee. And can you start question 16? Okay. Question 16. Yeah. Orange cost. Twice as much cost orange cost twice as much as apple. Which one are? Which one of the following does not cost the same? So what is other four? Okay. So basically it's saying which is the odd one out. Which is which was different. Yeah. Two. Cost means you cost the money you spend the money right Yeah. So cost twice, like I write, orange calls the toys as apple. So two oranges and three apples. But if you called an apple x for the cost of an apple. So the orange is two x. If the orange one of the orange is 1.5 and one apple one so just say just say x and two x, this is an it cost of an orange cost of an apple. So if you have two oranges and three apples, how many x's is that? How much is the cost in x? How much is the cost in x? It could be it could be a lot of number I mean if that costs the same. So. Basically you're saying, Hey. A costs how much using x? What does it a letter a you've got two oranges so you've got two x, two x and you've got three apples X X X Yeah. So the cost. Of two oranges and three apples is seven x pence or pounds, right? Yeah. So b is just seven apples. So that's xxxxx X X, that's the same, right? That's also Yeah so one orange and five apples. One orange is two egand five apple means X X X X X. It's four, it's also seven x. So next one, three oranges, three, two x, two x, two x and two x and one apple it's also same. So. Yeah four orange is eight x, so e is the old one out Yeah. Okay. Nice. All right. Here let's just go to this one first. Okay, it's a bit small on the part on the it's a bit small on the percentages there, but start with question 17. Excuse me. What is gets an answer of 700 mean. How that's the answer he receives the number he gets is that. So nearest to 100 minutes, it could be 99 or 101 right? Yeah that would be 100 would be the rounding right? Okay. So so these two could be nearest to 100. Okay. What so what the question is asking, what is the smallest number that rounds to 700? To the hundreds rounding place. Right? So. Okay. So what this question is basically saying what number would be the smallest number? The I could round to 700 if I'm rounding to the hundreds. 因。为。Right. Okay, no, because that's rounding to the nearest one. Okay. So what you've written to the nearest one is 700. Yeah. I would you say. Because we're looking I tell you why because we're looking here to round this to 700. We look here and we round it to the nearest one. Okay, Yeah. So that's 700 to the nearest one. Okay. So look, this is 700 to the nearest ten because we are looking between. These two numbers right I know I know the first one the first one is just the going to one and the second one is looking at five so five is going to one it almost to 702 okay Yeah so actually what we want to do is round to the nearest 100 okay? So in counting terms this means we are counting in 100 100, 200 so our numbers are going to be like the answers of our rounding are gonna to be we are counting to the nearest 100. So we are counting in 100, right? So it's saying which number would be 700? What's the smallest number, right? What's the smst? So you've either got 600 or 700. So some numbers are going to go to 600. Some numbers are going to go to 700. What's like? What's the number in between? You mean 650 it will be nwest to. Yeah so 650. Yes 649 it will be nearest to 600 right? So all of these anything under 650. Yeah, anything less than 650 is going here. Yeah any 650 or greater is going here. Yeah. Yeah so the smallest number it can possibly be is 650 right? Yes. What's the biggest number so big is the number it will be 749 right? Yeah, Yeah, okay, nice. All right. So that says, sorry, this is a bit small, this pie chart, but that says 20%. That his 20. 20% swimming. Is eight, right? Yeah, that one's twelve. Okay, I got it. I can't see it. Yeah. Nice, very nice, okay? I'm good at this. See. Yes, I'm good at this. Nice. Okay, so then this one. Okay. It's very silly. One tail. Even chance means a one only, right? Yeah even chance ces half 50% okay, definitely. I think a is. Yeah win and lose, it's always be a half. Yeah but do do all football teams. Have the same chance, right? Because all football teams can win or lose. So not only England, Yeah Yeah but it's not just that, is it? It's all football teams can win or lose. But what if what if like do you know what I mean? What if Jamaica plays Spain? Or Germany like do all do all countries have equally good football team? Yeah. So it will be sometimes it will be 30, 70. I know, I know. Yeah. Interthat, I get this one. Not this one. Not definitely. There's a greater than interest that I get five when a row a single size. Ce, what does c mean? Single bwhat. Even chance. Even chance is one half. Yeah, yes. Rolling a dice. This. Can you see this? No, wait, not that. Can you see this? Yes. Why can't I see it? Is there a more than 50% chance of getting a yes? What is the chance of getting a five? Six 100 divided by six. 100 divided by six equal 16 to 17 percent yes 17. So one of there's 15 out of six numbers. So this one is wrong. Yeah. It's not a half. There's less what is less than even chance. It means 31, 41Yeah means less than even. It means there are nothing no, this. Less than a half. Okay. Blue. Yes. Does that even chance that her baby will be born somewhere in the world in the next minute? Maybe yes. Is it definitely? Can we prove it? But we don't know yet. Let's look at right? We can't what's Yeah, we can't prove it though, can we? We can't prove it. Let's look, let's look right. Which one is the correct answer then can we look at b? It needs to be deep. Look at B No, because the chance of picking a blue ball is three blue balls out of it's up. Eve less. Chance of picking a blue? Bah, yes, I just see it in in pink. I don't know why. Yes, this is correct because 53 because. Let me see. Doesn't unless I think it's fayeah. So d is not correct, is it? Yeah, I think it's big. So right. So let's so we haven't got one answer being correct yet. Let's look at b okay. If you thif you throw a coin twice, you've got a head or tail, okay? There's throw one, that's throw two. Okay, so this is a throw. This is a head on throw one, a head on throw two, right? This is a tail, a tail on, throw one, a head on, throw two. This is a head on throw one, a tail on throw two. And this is a tail on throw one, a tail on throw two. Yes because the coin is a cover or a back cover. Yeah two sides. So in football match, it always play this first before the Yeah match. So look, it will be 5010 up. Yeah Yeah look, we've got four answers. Head, head, tail, head, tail, tail, head, tail. And there are four answers and there are two that have got one of each. Yeah, Yeah, so it's big, it's okay. Hold on, let me just copy this again and go here. All right, let's go to question 21. Yeah. Yeah 21. It takes a team of four people six hour to pay my fence. What is my fence? Like this but outside? Wooded wooded panel, wooden panels this is wood Yeah Woden panels going up Yeah. Three hour. Less than five hour, less than five. Sorry. It could be 16 people. It needs three hour. If you. Four people is six hours six hour divided by four it equal 1.5 of people, 1.51 people need one point. Stop. So. If there is 50 people. Oh, no. Well, Yeah, 15 people, 15 people, 15 people. If there is 15 people, it need. It's a bit awkward because we can't excuse me, we can't we cannot get the we haven't got a good multiple, have we? Yes. I know. I just know 1616 people can definitely finish less than five hour. Yeah. So so hold on. So it's twice as long. So four people. Four people would be twelve hours for this neighbor. Yeah. Twelve Yeah yes. So. I think we just need to go to one person, maybe. No sorry not one person. Yes so sorry one person would be three hours no would be 48 hours. Right? You need finish Yeah Yeah 48 if you finish in one person need 48 hour so two person need a half it will need a 20Yeah hour Yeah and so four would be twelve hours which we've already got. So 66 would be eight hours. Eight yes divided by 3:24 so eight need. Right? So seven. It's six hours can't finish, but eight hour could finish it. I think seven hour could finish. 77 people let's try 99 right? We just nine people. We're going to have to divide. I'll just use my calculator. Look, nine people right? Eight people are six hours. Yeah. Yes. So to get to nine people, we have to divide the six hours by eight. No. And times, times by nine, no, no other way round. The other way round, we have to divide the eight people by six hours. Yes eight divided by six. No no no sorry, sorry, sorry. I think it's six divided by eight. Yeah Yeah sorry. Six divided by eight. No, that's not right. Because it's giving us more time. I'm divided by people, the person or people Yeah people time divided by people. So eight divided by six. We ate eight divide ded by six. Yeah, but that's not right either, is it? Hold on, it's very confusing. I think just take it from the one person, right? As in when we go from one person to two people, we divide by two Yeah. Yeah Yeah. When we go from one person to four people, we divide by four. So if we do 48. One person to three people, we need 48 divided by three. That would be 40. 48 divided by six equal eight, right? So look, eight people is six hours because it's 48 divided by eight is six. So if we do 48 divided by nine people, it's still not enough, is it? 48 divided by three I is 16. 48 divided by three it will be 60Yeah so 48 divided by nine equal it's always five point. Yeah so five and a third hours, which is five hours, 20 minutes. Yeah. Yeah because a third of an hour okay, so five hours 20 minutes, so ten nine people is not enough. So ten people is enough right? 33 hour, 1010 people is 4.8 hours. Yeah which in time in time is how many minutes? Four hours? 48 minutes. Yeah. Because there is 60 minute 60y by a Yeah. So we have to count, we have to do it this or it's a good way to do it this way because obviously we can't have 9.5 people. That makes no sense. Yeah. So basically nine people. Nine people is not enough. Nine is not enough. Yeah ten. Ten is enough. Ten. Yeah Yeah ten because six will be a straight number. Yeah so we can't have decimals of a person. You can have decimals of time. But what's important is counting in whole people until we get to the required limit. Yeah so basically nine people would wouldn't be fast enough. Ten people would be fast enough. Yeah. Yeah. Okay. Right. This one. I feel you. Feel you. 8分之4分之三等于就12分之6，等于2分之72之。Have you spotted a pattern? 到32.48 7000 0的1010。点亮。Right right nice. Is if this pattern it's continue the sums that ever closer to the particular number. Right now, what does this question mean? Okay. So what are these numbers? They are actually getting more and more close to what. Yeah do you see to one? Yeah. Yeah. So they're getting closer to one. Yeah. Yeah. Have you seen it on a picture? Did you already look at that? Maybe you didn't. But look, if we think about it, it's it's just what do we call it? Geekery? Do you know what gekery means just for people who like playing around with numbers? If that's between zero one, Yeah, how can we? It's basically going, okay, so we're going halfway, then we're going halfway again, then halfway between those two, then halfway between those two, then halfway between those. This one is no way, but I think it isn't. Then halfway again, right? We probably need a thinner line. Then halfway, then halfway here, then halfway. It can never get to one. Yeah, together. It's very straight. It's very straight, but I think it will be finished in some day, some day, someday. Let's try again. Can we get there? Right? Can we get there? Halfway. Okay. Halfway. Okay. Halfway. This one is two long halfway and 2m. Half, half, half, half, halfway, halfway. I can't do it. I get have to zoom in and it just goes forever. Okay? So it's getting closer and closer to the limit, but never touching it. Okay. Great. Well, look, these Charlie, were all exam questions Yeah for entrance to secondary school. So I think you did really well on those. Yeah, there's lots of ideas for thinking, Yeah, okay. The last thing I would like you to do. Is can we put. Some axes. On here. Okay, so we've got y and x. Yeah so we're going to do a little bit of graphing to finish. Okay? So we need the x axis and the y axis. Okay, so can we make a table of values I want. Okay. So can we just let's make eight values? Okay, so I would like you to graph. So the x 's going here and the y's go in there. Yeah. Can you do 22x plus three? Okay. So we're given the x numbers. X is zero, one, two, three, four minus one minus two. If x is zero, how much is y? Hero is it? Y is two times the x plus three. If in this in this another number let me think x is one x is one so 25 just check you put in the right place. Zero x is zero. Yeah so five should go here right? A爷。So x if x is is two is one. Y it will be seven th Yeah. If x is three, it will be nine. So if x is minus one, minus one times two, it will be minus two, minus two plus three, it will be one. Right, just check me put in the right place. Minus one. So I should put it into here, no x, you were saying x is minus one. So it's gone right? Yeah, Yeah. So why zero put in there? Zero doesn't right? I don't understand if x if x is zero. Right. What's the answer to why you need to take two times x? My brain is stop. Oh, maybe you're just tired that, right? Yes. So here is. Minus one if minus here will be one and minus two. Minus two it will be minus four. Minus one here will be minus one, minus three times two, minus six, minus minus three. Okay, so do you see the pattern? You can check your numbers. It's going minus three, minus one, one, three, five, seven, nine. Yeah, it's going up in twos. Yeah the reason for that is because our gradient is two Yeah okay. So can you put can you plot can you put those on the graph? Just to finish, can you make some little spots? Can you make some dots and then join them? Okay, why minus three x minus three x minus three? It will be here, right? Minus three across in the other side and minus three down. Minus three across, minus three this way. Okay, and minus three this way. Yeah, that was correct. I ask you. So here. So here is here, right? And Yeah, there. Minus two and minus one. Minus two and x minus two is here and y minus two is here. So here, this and another one. -11. Y is one and x is minus two. Minus. So here and careful, zero. Careful. Minus one is x or minus one Yeah. It will be no minus one, -11. Y will be one and x will be minus one. So it's here and the x is zero, y is three, y is one, two, three. X is zero right, x is one x is one and y is y is 51, two, three, four, five. X is two and y is is what is seven? X is two and y is seven. One, one, two, three, four, five, six, seven. And x is one, two, three, x is three, why is nine? It always up to. So what you're describing is that our line is going through these points, right? Okay, great. Well look, I'm gonna cut that out and we will save it for next lesson. Okay, so let me just cut the whole thing out. Hold on. Right. I'm just going to do it like this. I'm going to put this on the board so we can start with this and use it next time. Yeah. Yeah, okay. Have a great week, Charlie. Thank you. Goodbye you. Bye.
