Question

Katie feeds her cat, Elmer, 2/3 of a cup of food each day. She buys a bag of cat food that contains 18 cups of dry

food. How many days will that bag of cat food last?

Answer 1

27 days it will last

Explanation:

Answer 2

27

Explanation:

Set up a proportion.

1 day / (2/3 cup) = x/ 18 cups Cross Multiply

1 day * 18 cups = 2/3 cup * x Multiply both sides by 3

1 day * 18 cups * 3 = 2x

54 day cups = 2x cups Divide by 2

54 day cups/2 cups = x

27 days (The cups cancel)
