Question

18 is 32% of what number w? what is w?

Answer 1

Given: 18 is 32% of a number

To Determine: The number

Let the number be w. Therefore:

`\begin{gathered} 32\%ofw=18 \\ (32)/(100)* w=18 \end{gathered}`
`(32w)/(100)=18`

`\begin{gathered} 0.32* w=18 \\ 0.32w=18 \end{gathered}`

Divide both sides by 0.32

`\begin{gathered} (0.32w)/(0.32)=(18)/(0.32) \\ w=56.25 \end{gathered}`

Hence,

an equation is 18 = 0.32 . w

The solution is w = 56.25
