If there are two thousand students at a university then according to the ratio there must be at least one hundred twenty five teachers. This is a simple math equation solved by dividing the total number of students by sixteen. The result of two thousand divided by sixteen is one hundred twenty five .

The correct answer is:

C. 125

Explanation:

The student to teacher ratio is 16:1.  This can also be written as 16/1.

We can use this to write a proportion and solve for the amount of teachers required.  We know that the total number of students is 2000, and the amount of teachers unknown; this gives us the ratio 2000/x.  This gives us the proportion

16/1 = 2000/x

Cross multiplying, we have

16(x) = 1(2000)

16x = 2000

Divide both sides by 16:

16x/16 = 2000/16

x = 125
