\[ \frac{9}{2} - 2 = \frac{5}{2} = 2.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{9}{2}\) and \(\frac{-2}{1}\) is \(2\). \[ \begin{aligned} \frac{9}{2} - 2 &= \frac{9 \cdot 1}{2 \cdot 1} + \frac{-2 \cdot 2}{1 \cdot 2} \\ &= \frac{9 + -4}{2} \\ &= \frac{5}{2} \end{aligned} \]
