So then let me divide these, and so this would get me to eighths. That looks like about a half, and then if I were to divide those, these would be fourths, and this is hand drawn, To represent these again, so how could I represent 3/8 of something, of a kilogram, in this case? Well, let me draw a rectangle here and I'm going to try toĭivide it into eighths, eight equal sections, so that looks about a half. All right, so the key is that we need to determine a reasonable estimate. So pause this video again and see if you can have a go at that. Determine a reasonable estimate for the weight of both fruits. So here, we are told that a banana weights 3/8 of a kilogram, an apple weighs 2/3 of a kilogram. That are more than a half, if you add them together, you're gonna have more thanĪ bag of chocolate chips. Something, that'd be a whole, so if you have two things So you can see that you'reĪdding two things together that are both more than a half. If you had a half, it would have been like this far. So 2/3 is more than a half, and then we also see thatĤ/5 is more than a half. So if we were to add these two together, do we have less than 1/2 of a bag, more than 1/2 of a bag,īut less than one bag, or more than one bag? Well, when you see even the first 2/3, where is a half? A half would have been right around there if we're talking about half of it. And now what does 4/5 look like? Well, it would be 1/5, 2/5, 3/5, and then 4/5.
I can divide this into fifths, so 1/5, 2/5, 3/5, and then 4/5, and 5/5. And 2/3 would be, that'sġ/3 right over there and then that is 2/3 right there, and what does 4/5 looks like? Well, let's see. It's hand drawn, so it's not perfect, but I think it gets the job done. Into three equal sections, so that is pretty close. Now what does 2/3 look like? Well, let me divide this So let's make, so this is a whole right over here, and then this is another

Now in the future, we will learn how to actuallyĪdd something like 2/3 to 4/5, but for the sake of this exercise, we just want to get good at estimating it. Out which of these choices is the best reasonable estimate of the total amount of chocolate chips. So pause this video and see if you can figure Determine a reasonable estimate of the total amount ofĬhocolate chips Tony has.
That Tony has 2/3 of a bag of dark chocolate chips and 4/5 of a bag of white chocolate chips.
