Question

The ratio of water to orange juice to cranberry juice in a punch bowl should be 2:5:3.

Answer 1

Water= 2
Orange juice= 5
Cranberry Juice= 3

Since the cranberry juice is 24 ounces, and 3 ounces in the other ratio, we know that 3*8=24, so we would multiply all of the others by 8. 

Cranberry juice: 3*8=24
Orange juice: 5*8= 40
Water: 2*8=16

So our ratio would be 16:40:24
