\[ 6 - \frac{3}{8} = \frac{45}{8} = 5.625 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{6}{1}\) and \(\frac{-3}{8}\) is \(8\). \[ \begin{aligned} 6 - \frac{3}{8} &= \frac{6 \cdot 8}{1 \cdot 8} + \frac{-3 \cdot 1}{8 \cdot 1} \\ &= \frac{48 + -3}{8} \\ &= \frac{45}{8} \end{aligned} \]
