Answer 2

21 students were in the class.

Explanation:

The information in the question tells you that 4/7 of the class is girls.

That means that the remainder of the class is 1 - 4/7 = 3/7 boys

Let the total in the class = x

(3/7)x = 9 Multiply by 7

(3/7)*7*x = 9 * 7 Simplify the right and left

3x = 63 Divide by 3

3x/3 = 63/3

x = 21

There were 21 students in the class.
