To find how many tutors are for 16 classes, we can use the next proportion:
[tex]\frac{2\text{ tutors}}{x\text{ tutors}}=\frac{4\text{ classes}}{16\text{ classes}}[/tex]Solving for x:
[tex]\begin{gathered} 2\cdot16=4\cdot x \\ \frac{32}{4}=x \\ 8=x \end{gathered}[/tex]There are 8 tutors for 16 classes
