\[ \frac{3}{4} - \frac{1}{8} - \frac{1}{2} = \frac{1}{8} = 0.125 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{4}\), \(\frac{-1}{8}\), and \(\frac{-1}{2}\) is \(8\). \[ \begin{aligned} \frac{3}{4} - \frac{1}{8} - \frac{1}{2} &= \frac{3 \cdot 2}{4 \cdot 2} + \frac{-1 \cdot 1}{8 \cdot 1} + \frac{-1 \cdot 4}{2 \cdot 4} \\ &= \frac{6 + -1 + -4}{8} \\ &= \frac{1}{8} \end{aligned} \]
