\[ \frac{3}{8} - \frac{2}{3} = - \frac{7}{24} = -0.291\overline{6} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{8}\) and \(\frac{-2}{3}\) is \(24\). \[ \begin{aligned} \frac{3}{8} - \frac{2}{3} &= \frac{3 \cdot 3}{8 \cdot 3} + \frac{-2 \cdot 8}{3 \cdot 8} \\ &= \frac{9 + -16}{24} \\ &= \frac{-7}{24} \end{aligned} \]
