Quizplus · Accepted Answer

To add fractions, you need a common denominator. The least common multiple of 13 and 8 is 104. Convert each fraction: $\frac{4}{13} = \frac{4 \times 8}{13 \times 8} = \frac{32}{104}$ and $\frac{3}{8} = \frac{3 \times 13}{8 \times 13} = \frac{39}{104}$. Adding these gives $\frac{32}{104} + \frac{39}{104} = \frac{71}{104}$.
