#### Answer

$\displaystyle \frac{5}{100}=\frac{32}{n}$
(We are asked not to solve for $n$, so we stop here.)

#### Work Step by Step

We know that 5% of the medical exams is 32. Thus, to find out the total number of exams, we set up a proportion:
$\displaystyle \frac{5}{100}=\frac{32}{n}$
Where $n$ is the total number of exams.
