Question

423 is 45% of what number? round your answer to the nearest hundredth, if necessary.

Answer 1

We are looking at the number that when evaluated its 45%, we get 423. We let x be that original number. If we multiply x by 45%, or 0.45, we must get 423. We can write an equation representing this as

`0.45* x=423`

Solve for the value of x, we have

`\begin{gathered} \frac{\cancel{0.45}x}{\cancel{0.45}}=(423)/(0.45) \\ x=(423)/(0.45) \\ x=945 \end{gathered}`

Thus, the original number is equal to 945.

Answer: 945
