\[ \frac{5}{2} - 1 = \frac{3}{2} = 1.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{5}{2}\) and \(\frac{-1}{1}\) is \(2\). \[ \begin{aligned} \frac{5}{2} - 1 &= \frac{5 \cdot 1}{2 \cdot 1} + \frac{-1 \cdot 2}{1 \cdot 2} \\ &= \frac{5 + -2}{2} \\ &= \frac{3}{2} \end{aligned} \]
