What expression represents '' five times the quotient of some number and ten"? A. 5 (z/10) B. 5 (z-10) C. 5 (10/z) D. 5 (10-z)

Five times the quotient means you have to do the quotient first which is the answer to a division problem. The 5 must be outside the parenthesis.

Next it says some number, this is the variable, and 10.

You have to go in the order it's given so

5 (z/10) is the answer.

Letter A

I think it's a or c.
