\[ 1 + \frac{7}{2} = \frac{9}{2} = 4.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{1}\) and \(\frac{7}{2}\) is \(2\). \[ \begin{aligned} 1 + \frac{7}{2} &= \frac{1 \cdot 2}{1 \cdot 2} + \frac{7 \cdot 1}{2 \cdot 1} \\ &= \frac{2 + 7}{2} \\ &= \frac{9}{2} \end{aligned} \]
