Question

at one time the student-to-faculty ratio at Centennial Academy was 17 :3 . the total number of students and faculty was 740. how many faculty members were there? how many students were there?

Answer 1

The number of faculty was 3/(17+3) = 3/20 of the total of students and faculty.

The number of faculty members was (3/20)·740 = 111.

The number of students was 740 - 111 = 629.
