\[ \frac{3}{8} + \frac{1}{2} - \frac{5}{8} = \frac{1}{4} = 0.25 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{8}\), \(\frac{1}{2}\), and \(\frac{-5}{8}\) is \(8\). \[ \begin{aligned} \frac{3}{8} + \frac{1}{2} - \frac{5}{8} &= \frac{3 \cdot 1}{8 \cdot 1} + \frac{1 \cdot 4}{2 \cdot 4} + \frac{-5 \cdot 1}{8 \cdot 1} \\ &= \frac{3 + 4 + -5}{8} \\ &= \frac{2}{8} \\&= \frac{1}{4} \end{aligned} \]
