Question

A serving of dried fruit is 1/5 cup. A bag contains

9/10
cup of dried fruit. Which
division expression can you use to find the number of servings in the bag:
1/5 divide 9/10 or 9/10 divide by 1/5 ? Explain your reasoning.

Answer 1

9/10 divide by 1/5

4 1/2 cups

Explanation:

Serving of dried fruits = 1/5 cups

Bag of dried fruits = 9/10 cups

Expression that can be used to find the number of servings in the bag = Bag of dried fruits / Serving of dried fruits

= 9/10 ÷ 1/5

= 9/10 × 5/1

= (9* 5) / (10 * 1)

= 45/10

= 4 5/10

= 4 1/2 cups

9/10 divide by 1/5
