Question

A recipe uses 4 cups of milk to make 12 servings. If the same amount of milk is used for each serving, how many servings can be made from three gallons? How many cups will you need to find the number of servings for?

Answer 1

144 servings

Explanation:

1 gallon = 16 cups

2 gallons = 32 cups

3 gallons = 48 cups

Using ratio

4 cups of milk : 12 servings

48 cups of milk : x servings

4 : 12 = 48 : x

4 / 12 = 48 / x

Cross product

4 * x = 12 * 48

4x = 576

x = 576 / 4

= 144

x = 144 servings

3 gallons of milk = 48 cups of milk = 144 servings
