The correct answer is:
C. 125
Step-by-step 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
