Question

1. June bought some books for $51. This was ⅗ of hermoney. How much money did she have to beginwith?

Answer 1

Since $51 was 3/5 of her money, then if we multiply 3/5 by the amount of money she had, x, we should obtain 51.

`(3)/(5)x=51`

We can then solve the above equation for x.

`\begin{gathered} 3\cdot x=51\cdot5 \\ 3\cdot x=255 \\ x=(255)/(3) \\ x=85 \end{gathered}`

She had $85.
