Question

#2 A punch recipe calls for

2 parts soda to 3 parts fruit
juice. If you use 8 cups of
soda, how much fruit juice
do you need?

Answer 1

2x4=8 3x4=12 cups fruit juice

Answer 2

You would need 12 cups of fruit juice.

Explanation:

Keeping the fraction/ratio the same of 2:3, you have to make the expression 8:?. 8 is 4 more times than 2, so you would have to multiple 3 4 times as well, and get 12 :).
