Answer 1

To find how many tutors are for 16 classes, we can use the next proportion:

$\frac{2\text{ tutors}}{x\text{ tutors}}=\frac{4\text{ classes}}{16\text{ classes}}$

Solving for x:

$\begin{gathered} 2\cdot16=4\cdot x \\ \frac{32}{4}=x \\ 8=x \end{gathered}$

There are 8 tutors for 16 classes
