\[ \frac{13}{16} - \frac{3}{8} = \frac{7}{16} = 0.4375 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{13}{16}\) and \(\frac{-3}{8}\) is \(16\). \[ \begin{aligned} \frac{13}{16} - \frac{3}{8} &= \frac{13 \cdot 1}{16 \cdot 1} + \frac{-3 \cdot 2}{8 \cdot 2} \\ &= \frac{13 + -6}{16} \\ &= \frac{7}{16} \end{aligned} \]
