Question

answer the following questions.
(a) 52.5% of what number is 25.83?
(b) what percent of 61 is 152.5?

Explanation:

Step1: Define unknown for (a)

Let $x$ = target number.
$0.525x = 25.83$

Step2: Solve for $x$ (a)

$x = \frac{25.83}{0.525}$
$x = 49.2$

Step3: Define unknown for (b)

Let $p$ = target percent.
$\frac{p}{100} \times 61 = 152.5$

Step4: Solve for $p$ (b)

$p = \frac{152.5}{61} \times 100$
$p = 250$

Answer:

(a) $49.2$
(b) $250\%$
