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.
