Question

Find the unknown quantity in the following percent problem using the formula R.B= A. Round your answer to two decimal places, if necessary. 75% of what number is 165?

Answer 1

In order to calculate the number wanted, let's use the values of R = 0.75 (that is, 75%) and A = 165 in the given formula. Then, we solve it for B.

So we have:

`\begin{gathered} 0.75\cdot B=165 \\ B=(165)/(0.75) \\ B=220 \end{gathered}`

Therefore the number wanted is 220.
