$$\frac{1}{2} + \frac{1}{8} = \frac{5}{8} = 0.625$$

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of $\frac{1}{2}$ and $\frac{1}{8}$ is $8$. $$\begin{aligned} \frac{1}{2} + \frac{1}{8} &= \frac{1 \cdot 4}{2 \cdot 4} + \frac{1 \cdot 1}{8 \cdot 1} \\ &= \frac{4 + 1}{8} \\ &= \frac{5}{8} \end{aligned}$$
