For every girl taking classes, there are 3 boys who are taking classes. if there are 236 students taking classes, write and solve a proportion to predict the number of boys taking classes

The ratio of boys to girls is 3:1

so divide your total amount of students (236) by 4.

That will give you 59. That represents the amount of girls.

If you multiply 59 by 3 (because there ratio is 3:1) you will get the amount of boys.

59*3=177

So to sum up, the ratio of boys to girls is 3:1, making 177 boys taking classes and 59 girls taking classes.
