 What is half of six? Three. But do we have three parts of that six? We have four six. All right, so we have more than that half. All right, so what if I were to add a twist to that question? What if I were to ask how much longer in seconds, and this is where we have to be mindful of the units. In seconds, does making breakfast take then doing my hair? What I want you to do is I want you to turn and talk within your group for about a minute and discuss this. What would you do? I think it's 10 seconds because if you multiply, if there's 60 seconds in a minute, if you multiply 6 times 10, it gives you 60 and 10 times 4 is 40, and if you multiply one half times 30, it's gonna give you 30 over 60, and if you subtract 30 over 60 plus 40 over 60, or minus 40 over 60, it will give you 10 over 60, so 10 seconds more. What does a 60 represent? Is it a minute or second? Seconds. That it takes to make breakfast. 60 seconds equals? Equals a minute. Equals a minute. So the numerator is gonna be the second. Yeah, so it's seconds over the second that it equals to make one minute. Five, four, three, two, one. What are our ideas? What are ideas in in solving this part of the question? How much longer did the longer activity making breakfast take? Davino, what are you thinking? What is the strategy? What do you think we can do to solve that? My group discussed that we could change it into common denominators, which would be 60, because one minute equals 60 seconds, and then we could divide 60 by 6, and that gives us 10. So actually, can you come up here and show what you're thinking to everyone? One half, and get a common denominator of 60, which would be... Very precise, I like that. I give you 30 over 60, and if you simplify that, you get, by 30 you get one half, no. You get one half, and... But you go back to what you had before, right? And then four, six, times 10. It gives you 40 over 60. That means out of one minute, that's 30, because 60 is... 60 seconds is one minute, and that's 30 seconds. So doing my beautiful hair takes how long in seconds? 30 seconds. 30 seconds, and what about making my breakfast? 40 seconds. So now let's answer the question. How much longer does it take for me to make my breakfast than comb my hair? It takes you 30 seconds to do your hair, and then it takes you 40 seconds to do and make your breakfast. If you subtract 40 by 30, you get 10, so you get 10 seconds longer. 10 seconds longer too, be precise. Do your hair. 10 seconds longer too. Do your hair. Do my hair. Let me make your breakfast. Let me make my breakfast, okay? Very good.
