Final answer:
The correct answer is a) 1.5 cups. Dividing the total amount of milk (9 cups) by the number of servings (6), we find that each serving requires 1.5 cups of milk.
Step-by-step explanation:
To determine how much milk is needed for each serving in a recipe that serves 6 and requires 9 cups of milk, we can perform a simple division:
9 cups of milk ÷ 6 servings = 1.5 cups of milk per serving.
A recipe that serves 6 requires 9 cups of milk. 1.5 cups milk is needed for each serving. Therefore, the answer is (a) 1.5 cups of milk for each serving.
