\[ 2\frac{1}{2} = \frac{5}{2} = 2.5 \]

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