Question 46751: Student-teacher ratio. The student/teacher ratio for Washington High was reported to be 27.5 to 1. If there are 42 teachers, then how many students are there?

This can't be as simple as 42*27.5 is it?

Yes, because
For every 1 teacher there are (1)(27.5) students.
For every 2 teachers there are (2)(27.5) or 55 students, etc.
This is a proportion problem:
27.5/1 = x/42 [Solve for x students]
(27.5)(42)=1x
1155 =x
