Question

in a classroom there are 56 boys and 72 girls, find the ratio of girls to the total number of students.​

Answer 1

Answer:
`(9)/(16)`

Explanation:

We need to find the ratio of girls to the total number of students. That means our ratio is going to be 72 (the number of girls) over 56+72 (boys + girls, the total number of students).

When you add 56+72, you'll get 128 in the denominator. Continuing to simplify the fraction, you'll end up with:

`(72)/(128)` =
`(9)/(16)`

Depending on what format your teacher wants, this can be written as
`(9)/(16)` or 9:16.
