In jenny's class, there are 24 students. of these, 5/8 are girls. how many girl's are in jenny's class?

There are 24 student and we need to find out 5/8 of the class. So simply it is:

5/8 of 24

First we need to find out 1/8 of 24 so we do

24÷8

Which is: 3

But we want to 5/8 so we do

3×5

Which is: 15

So the amount of girls in Jenny's class is 15.

Hope it helps :)
