Answer 5

@JakeV8 I got 8

Answer 6

Ok, I'm just now reading it... how did you get 8?

Answer 7

I mutiply cross right?

Answer 8

First, I would make 4 1/3 into an improper fraction... 4 is 12/3, right? so 4 1/3 is = 13/3

And you want to know how many FULL pieces of 2/3 length come out of that 13/3...

So you want to divide: 14/3 divided by 2/3\[\frac{ 14 }{ 3 } \div \frac{ 2 }{ 3 } = \frac{ 14 }{ 3 } \times \frac{ 3 }{ 2 }\]

Answer 9

sorry, I messed up that equation... wrote "14" instead of "13" in both places :(

Answer 10

This is correct:\[\frac{ 13 }{ 3 } \div \frac{ 2 }{ 3 } = \frac{ 13 }{ 3 } \times \frac{ 3 }{ 2 }\]

Answer 11

39/8

Answer 12

the bottom is 6, not 8.

But rather than do that, cancel the 3 on top with the 3 on bottom... you get 13/2

Answer 13

So B is the correct answer.

Answer 14

No?

If you can cut 13/2 pieces of wood, that means you are cutting 6.5 pieces. But that last half piece doesn't count... you are asked how many FULL pieces you can cut. So it's only 6 full pieces.
