the student-to-faculty ratio at a small college is 17:3. The total of the students and faculty is 740. How many faculty members are there at the college? How many Students?
Ratio of student to teacher = 17:3
Let the total number of students and faculty = x
Then
Number of students = 17X
Number of teachers =3X
So 17X+3X=740
20X = 740
X = 37
Then the number of students = 17*37
= 629 Number of teachers = 3*37
=111
