Quizplus · Accepted Answer

To add fractions, they must have a common denominator. The least common multiple (LCM) of 15 and 25 is 75. Convert each fraction: $\frac{11}{15} = \frac{11 \times 5}{15 \times 5} = \frac{55}{75}$ and $\frac{1}{25} = \frac{1 \times 3}{25 \times 3} = \frac{3}{75}$. Adding these gives $\frac{55}{75} + \frac{3}{75} = \frac{58}{75}$.
