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