Quizplus · Accepted Answer

To subtract these fractions, they must have a common denominator. The least common multiple of 5 and 4 is 20. Converting each fraction: $\frac{9}{5} = \frac{36}{20}$ and $\frac{1}{4} = \frac{5}{20}$. Subtracting these gives $\frac{36}{20} - \frac{5}{20} = \frac{31}{20}$.
