There are 3 counselors for every 45 students enrolled in a camp. What is the maximum number of students allowed if there are 10 counselors? #HW

Make it a ratio.

3:45

Then, you make another ratio.

10:x

You want to find the x so that the first ratio is still valid.

3 multiplied by what equals 10? It is not a pretty number so put it in fraction form, 10/3.

Multiply 45 by 10/3.

Therefore, the maximum number of students allowed is 150.
