\[ 1 - \frac{5}{8} = \frac{3}{8} = 0.375 \]

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