Quizplus · Accepted Answer

To add fractions with different denominators, find a common denominator, which in this case is 91 (13 * 7). Convert each fraction: $\frac{9}{13} = \frac{9*7}{91} = \frac{63}{91}$ and $\frac{1}{7} = \frac{1*13}{91} = \frac{13}{91}$. Adding these gives $\frac{63}{91} + \frac{13}{91} = \frac{76}{91}$.
