## Algebra 1: Common Core (15th Edition)

The student flipped the numerator and the denominator; it should actually be $\frac{n}{5}$.
When a phrase asks for "the quotient of" two numbers or variables, the first one listed should be on top of the fraction (the numerator) while the second one listed should be at the bottom of the fraction (the denominator). Thus, it should be $\frac{n}{5}$, not $\frac{5}{n}$.
