未来形

- [Instructor] So what we're going to do in this video

命令形

but instead of a question mark, I'll just put a letter.

What does y need to be to make this true?

And before I tell you go go pause this video

So let's try to represent 3/4, or I'll represent it for you.

So I'm going to divide it into four equal sections.

So let's see, that would be dividing it roughly in half.

I'm hand-drawing it, so it's not perfect,

The areas of each of these sections should be equal.

So there you go, this is my hand-drawn version of that.

And so three of those four, and I will do that in purple.

two, and then just for kicks I will do this one out here.

So if I were to think about this in terms of eighths.

But this time instead of just splitting them into fourths,

just 'cause it's easy to look at the one above that.

And then I'll divide each of the fourths into two.

The drawing is really the hardest part here.

But imagine if there were eight equal sections.

Pause the video and try to work it out on your own.

All right, well, we can just look at this visually.

So this first fourth, we could say that's equivalent

to filling out this eighth and this eighth.

Well, I have one, two, three, four, five, 6/8.

So what we could see here in this top circle

is we've divided it into six equal sections.

So each of these are one of the six equal sections or 1/6.

And we can see that one, two, three, four

So what we have represented in that top circle,

So once again, how many thirds are equivalent to 4/6?

Instead of just putting a question mark there,

So what should x be for these two things to be equivalent?

what I am circling in the orange up here.

so now I would have this would be 1/6 and that would be 1/6.

And that is equivalent to two of these sixths.

So we could say those two sixths are equivalent

And it's a little tricky because they didn't put

but you could imagine if we were to move.

So if I were to move that sixth to right over here.
