In your math class, 60% of the students are girls. If there are 15 girls in the class how many students are in your math class?

60 % is  0.6

0.6 x = 15

x = students in class = 15/(0.6) = 25

15/60%=25

Well it is 60% so you are going to turn 60% into a fraction => 60/100 then multiply it by 15 which equals 25
