Quizplus · Accepted Answer

To add the mixed numbers, first convert them to improper fractions: $7 \frac{2}{3} = \frac{23}{3}$ and $3 \frac{3}{7} = \frac{24}{7}$. Find a common denominator, which is 21, and convert: $\frac{23}{3} = \frac{161}{21}$ and $\frac{24}{7} = \frac{72}{21}$. Adding these gives $\frac{233}{21}$, which simplifies to $11 \frac{2}{21}$.
