\[ \frac{15}{16} - \frac{9}{12} = \frac{3}{16} = 0.1875 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{15}{16}\) and \(\frac{-9}{12}\) is \(48\). \[ \begin{aligned} \frac{15}{16} - \frac{9}{12} &= \frac{15 \cdot 3}{16 \cdot 3} + \frac{-9 \cdot 4}{12 \cdot 4} \\ &= \frac{45 + -36}{48} \\ &= \frac{9}{48} \\&= \frac{3}{16} \end{aligned} \]
