\[ \frac{3}{4} - \frac{1}{2} = \frac{1}{4} = 0.25 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{4}\) and \(\frac{-1}{2}\) is \(4\). \[ \begin{aligned} \frac{3}{4} - \frac{1}{2} &= \frac{3 \cdot 1}{4 \cdot 1} + \frac{-1 \cdot 2}{2 \cdot 2} \\ &= \frac{3 + -2}{4} \\ &= \frac{1}{4} \end{aligned} \]
