Answer
$30\%$ of $41.67$ is $12.5$
Work Step by Step
$a=p\%.b$
$12.5=30%.b$
$12.5=0.3.b$
$b \approx 41.67$
$30\%$ of $41.67$ is $12.5$.
Using the Percent Proportion:
$\frac{a}{b}=\frac{p}{100}$
$\frac{12.5}{b}=\frac{30}{100}$
$30b=1250$
$b \approx 41.67$
$30\%$ of $41.67$ is $12.5$.
The two methods give the same result.
