3 parts juice to 2 parts ginger ale makes a total of 5 parts.
3/5 is the ratio for juice.
2/5 is the ratio for ginger ale.
For 15 gallons,
(3/5)*15=9 gallons of juice is needed.
(2/5)*15=6 gallons of ginger ale is needed.

There are 5 parts altogether 3 fruit juice and 2 ginger. So 2/5 of the 15 gallons needs to be ginger
:
2/5(15)=6 gallons

---------------------
juice is to ale as 3 is to 2, which is the same as 3x to 2x.
Equation 3x + 2x = 15 galloms
5x = 15
x = 3
So fruit = 3x = 9 gallons
And ale = 2x = 6 gallons
