Question

There are five boys to every seven girls in an introductory geology course. If there are 408

students enrolled in the course, how many are boys?

Answer 1

170 boys

Explanation:

If there are five boys to every seven girls, then one group will have a total of 12 students.

Therefore, there are 5*34 = 170 boys
