Question

There are 16 girls in Ms. Bentley's college math class. If 25% of the students are girls, what is the best estimation for the number of boys in the class?

A. 30

B. 40

C. 50

D. 60

Answer 1

C. 50

Explanation:

First, make a proportion.

16/x = 25/100

where x = total number of students

solving for x, we get x = 64.

64 - 16 girls = 48 boys
