\[ \frac{7}{8} - \frac{12}{16} = \frac{1}{8} = 0.125 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{7}{8}\) and \(\frac{-12}{16}\) is \(16\). \[ \begin{aligned} \frac{7}{8} - \frac{12}{16} &= \frac{7 \cdot 2}{8 \cdot 2} + \frac{-12 \cdot 1}{16 \cdot 1} \\ &= \frac{14 + -12}{16} \\ &= \frac{2}{16} \\&= \frac{1}{8} \end{aligned} \]
