Question

I need help on the last one. I have learned this before but it was a while ago. I just need to know how to set up the equation.

Answer 1

Use ratio ballet over hip hop

8/12= 1/X
Cross multiply
8x=12
Divide by 8
X= 3/2
So for each it's 1 1/2 one and one half

Answer 2

Draw 8 squares and then underneath it 12. Separate it so for every amount of this, there is an amount of this. Make sure they are even.
