Question

2 of 5

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many students are boys?

Answer 1

There are 15 boys in the class.

Explanation:

There are several ways to solve this, but here's how I did it:

5 (boys) : 7 (girls) = 12 students. There are 26 students, so we need to multiply this by 3.

15 (boys) : 21 (girls) = 36 students.

Answer 2

15

Explanation:

The ratio has been simplified so it may be hard to read.

To fix this multiply both the 5 and 7 by 3

This will give you 15:21

15 + 21 = 36 which is the total number of students.

Keeping the ratio in the same order means that there are 15 boys.
