Answer 1

Write an expression when doing percentage questions to help clarify what's being asked for and you'll get to
`x=15/.25=60`

Explanation:

We're asked to figure out what number it is that if we take 25% of it we get 15 (remember that 25% can be written as a decimal of .25):

`x(0.25)=15`

Let's solve for x:

`x=15/.25=60`
