Question

3/5 of the students in a classroom are girls. If there are ten boys in the class, how many total students are there?

Answer 1

if 3/5 are girls, then 2/5 are boys

2/5 of total students = 10
2/5x = 10
x = 10 * 5/2
x = 50/2
x = 25 <== 25 total students

Answer 2

25 students are in the classroom. 25= 10 students, meaning that 1/5=5 students, and that 3/5 means 15. 3/5+2/5=5/5 which equals 25.
