Question

Mrs. Lee is fixing a large casserole for a potluck dinner. She is making 50 servings. Each serving requires 0.03 kilogram of rice. How much rice should Mrs. Lee use? Please help

Answer 1

You need to set up a proportion.

1 serving / 0.03 kg = 50 servings/ x Cross multiply

x*serving = 0.03 kg * 50 servings Divide by serving

x = 0.03 kg * 50 servings / servings

x = 0.03 kg * 50

x = 1.50 kg
