Answer
A good phrase would be: "The quotient of y and 5."
Work Step by Step
In the expression $\frac{y}{5}$, we are dividing two things. Thus, we use the phrase "the quotient" and list the two things, y and 5, by listing the numerator (the top of the fraction) first. Therefore, a good phrase would be: "The quotient of y and 5."
