Hey classes nine boys and 15 girls the righ hey classes nine boys and 15 girls what is the ratio in simplest form that compares number of boys to total number of students

Hello!

A ratio is a comparison of two values. This is comparing boys to total students. In each class, there are nine boys. With fifteen girls as well, this makes twenty four students. 

This gives us the ratio 9:24

Note that both can be divided by three, so we get thus.

3:8 is the ratio of boys to total students.

I hope this helps!
