Answer:
3/10 gallons
Explanation:
We know that the recipe for 1 serving calls for 3/5 gallons of milk.
We want to know what 1/2 a serving calls for. Let's set up a proportion:
(1/2) / 1 = x / (3/5) , where x is the amount of milk needed for 1/2 the recipe
Cross-multiply:
x * 1 = (1/2) * (3/5)
x = 3/10
The answer is thus 3/10 gallons.
