Arecipe calls for 10 cups of oatmeal. benjamin wants to make 1/5 fewer servings than the recipe makes. which expression represents how many cups of oatmeal benjamin should use?
a. 0.8 * 10
b. 1.8 * 10
c. 0.2 * 10
d. 1.2 * 10

A. 0.8 * 10

1/5 fewer means 20% less than the original number of cups.

100% - 20% = 80% of the original recipe should be used by benjamin.

80% x 10 or 0.80 x 10 = 8 cups.

0.2 * 10 is the expression that represents the decrease in the measurement of cups.
