Question

3/4 of the students in a classroom are girls. If there are ten boys in the class, how many total students are there?

Answer 1

40 students total

Explanation:

Let s represent the total number of students. Then (3/4)s are girls and (1/4)s are boys. Using the info on boys, (1/4)s = 10. Thus, s = 40 (students).

Check: Is (1/4)(40) = 10? Yes.

Is (3/4)(40) = 30? Yes

Is 10+30 = 40 (students)? Yes
