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

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