What does this expression represent five times the quotient of some number and ten

A. 5 (10/z)

B. 5 (z/10)

C. 5 (10-z)

D. 5 (z-10)

If we break down the problem if basically gives the answer:

five times the quotient of some number and ten

5 times (any variable) divided by 10

The answer is B. The answer isn't A because you have to go in order of what the question states. It didn't say ten first. It can't be C or D because those are not quotients.
