I’m trying to help me daughter with her homework and I don’t know how to figure this. Thank you for any help so I can lead her down the right path.

Answer:
25 = total number of paintbrushes
Step-by-step explanation:
number with yellow handles = total number of paintbrushes * percent with yellow handles
We know that 15 have yellow handles and the percent with yellow handles is 60
15 = total number of paintbrushes * 60%
We need to change the percent to a decimal
15 = total number of paintbrushes * .60
Divide each side by .60
15/.60 = total number of paintbrushes * .60/.60
25 = total number of paintbrushes
