A macaroni and cheese recipe calls for 1/4 cup of flour for every 1 1/6 cup of milk. To make a bigger batch, the chef uses 5 cups of flour.Which of the following would be the amount of milk needed for the bigger batch?
Answer Choices:
Correct Answer:
23 1/3 cups
Rationale:
Set up proportion: (1/4 cup flour) / (1 1/6 cup milk) = (5 cups flour) / (x cups milk)
Cross multiply: 5 × (1 1/6) = (1/4) × x
Solve for x: x = (5 × 7/6) ÷ (1/4) = 23 1/3 cups
