Question #5fe42

Answer 1

There are `12 boys and 8 girls`.

Explanation:

When you start with a ratio of a total sum, you are given the fraction of the total sum that each component takes up or occupies.

In this case, the ratio is 3B:2G which is also `3+2=5` or `5/5*20`

So for boys: `3B/cancel5*cancel(20)4=3B*4=12B`

And for girls: `2G/cancel5*cancel(20)4=2G*4=8G`

Total students: `12B+8G=20`
