Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

`(3)/(5) = (24)/(x)`

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.

Answer 2

40 girls

Explanation:

Set up a proportion where x is the number of girls in band class:

`(3)/(5)` =
`(24)/(x)`

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.
