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

Answer:

40 students total

Step-by-step 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
