\[ 8 - \frac{3}{4} = \frac{29}{4} = 7.25 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{8}{1}\) and \(\frac{-3}{4}\) is \(4\). \[ \begin{aligned} 8 - \frac{3}{4} &= \frac{8 \cdot 4}{1 \cdot 4} + \frac{-3 \cdot 1}{4 \cdot 1} \\ &= \frac{32 + -3}{4} \\ &= \frac{29}{4} \end{aligned} \]
