Question

A preschool has a student to teacher ratio of 5:2. Which of the following ratios is equivalent to this ratio?

A.
45 teachers to 18 students

B.
45 students to 18 teachers

C.
35 students to 10 teachers

D.
10 students to 7 teachers

Answer 1

Answer: 45:18 & 35:10, B & C

Explanation:

In the question, it says a student-to-teacher ratio so that would eliminate A. Then you would divide each answer by 5 and 2 and see if it is divisible.

For Example:

45/5 and 18/2 you would get 9 and 9

35/5 and 10/2 you would get 7 and 5

10/5 and 7/2 you would get 2 and a decimal/fraction meaning it is not equivalent

So your answers would be B & C
