\[ \frac{5}{8} - \frac{2}{4} = \frac{1}{8} = 0.125 \]

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