I would use ratio, so girls on the left as 3 and boys on the right as 1. As their is 3 times as many girls compare to boys. Add these 2 numbers together and this makes 4 parts to the ratio. Now divide 24 by 4 and that gives you 1 part. Then multiply it by 3 to get 3 parts to get the amount of girls.

Answer:

18 girls.

Step-by-step explanation:

Let X represent the number of girls. Since there are three times as many girls, you'll use 3x.

Total students = Total number of girls + Total number of boys

3x + x = 24

4x = 24

x = 24/4

x = 6

 Number of boys = 6

 Number of girls = 3x = 3 x 6 which equals 18.
