Quizplus · Accepted Answer

First, convert the mixed numbers to improper fractions: $7 \frac{7}{11} = \frac{84}{11}$ and $5 \frac{13}{15} = \frac{88}{15}$. To add them, find a common denominator, which is 165. So, $\frac{84}{11} = \frac{1260}{165}$ and $\frac{88}{15} = \frac{968}{165}$. Adding these gives $\frac{2228}{165}$, which simplifies to $13 \frac{83}{165}$.
