- [Instructor] So which of the following numbers

The comparative

The imperative

All right, now let's think about this together.

And the way that I can best think about it

And then let's say that this is another whole

right over there, I'm gonna try to make these rectangles

Well, I would divide this whole into three equal sections.

And so I'm gonna try to divide it into three equal sections.

So that's three equal sections right over there.

Now they're supposed to be three equal sections,

these are hand-drawn so give me a little slack.

But one of these three equal sections, well that's 1/3.

Well then I would try to divide this in five equal sections.

And so 1/5 would be just one of these fifths.

So when you compare it like this, what's larger 1/3 or 1/5?

covers more of the whole, it's a larger fraction

And so you might have noticed an interesting pattern

You might have been tempted when you saw the five here,

five is larger than three, but 1/5 is less than 1/3

Because you're dividing your whole into more equal chunks.

if it's one of three of the whole, 1/3 of the whole,

or if it's one of three equal chunks of the whole,

so 2/3 is definitely going to be bigger than 2/5,

We have the same numerator, but the denominator is smaller.

So four of the bigger things is going to be larger
