Question 8 • Grade 7 Mathematics

Chen is baking muffins and banana bread for a brunch buffet. He needs 3 and 1 fifth cups of flour to make the muffins and 3 and 2 thirds cups of flour to make the banana bread. Which is the best estimate of the number of cups of flour that Chen needs to bake both recipes?

Answer
A
7 cups of flour
B
6 cups of flour
C
9 cups of flour
D
8 cups of flour

Explanation

Add the amounts of flour: 3 1/5 + 3 2/3 = 3.2 + 3.67, which is about 6.87 cups. Rounded to the nearest whole cup, that is 7 cups, so the best estimate is 7 cups of flour.
