The imperative

Pause this video and see if you can work that out.

that means that I'm taking three of these things

Now, I could also view this as each of these 2 1/4

is two plus 1/4 plus two plus 1/4 plus two plus 1/4.

All I did is I broke up each of the 2 1/4

two plus two plus two is going to be equal to six.

And then, if I were to take 1/4 plus 1/4 plus 1/4,

I have 3/4, so it's gonna be six plus 3/4,

Now, another way that we could have approached this

I could have rewritten that as the same thing as two is 8/4,

And so, this is going to be the same thing

as 9/4, 8/4 plus 1/4 is 9/4, times three.

And so, we could say, "Hey, that's just going to be equal

"to 9/4 plus 9/4 plus 9/4, which would be equal to what?"

this is going to be nine plus nine plus nine fourths,

"Hey, these look like they are different",

24/4 plus 3/4, which is exactly equal to 27/4.
