There are 35 girls and 25 boys in the class.

Step-by-step explanation

The ratio of girls to boys is 7 : 5

So, lets assume that the number of girls is
7x and the number of boys is
5x

Given that the total number of students in the class is 60. That means...


7x+5x=60\\ \\ 12x=60\\ \\ x= (60)/(12)=5

So, the number of girls,
7x= 7(5)=35

and the number of boys,
5x= 5(5)=25
