Which verbal expression best describes the algebraic expression 3x ÷ 5? a. the quotient of three times some number and five b. the product of some number and five divided by three c. the quotient of three and some number times five d. the sum of three and some number divided by five

That would be the quotient of 3 times some number  and 5.

Note the quotient is the result of a division . In this case its a division by 5.

The answer is A
This is the right answer because the quotient means to divide. So in other words A is saying, 3 time some number divided by 5. 
B is not right because it is saying that 5 and some number are being multiplied and then divided by 3. 
C is not correct either because it is saying that you are first dividing 3 byy some number, then multiplying the product of that by 5.
D is also not correct because it is adding 3 and some number then dividing by 5 (when it should be multiplying).
