\[ 1 - \frac{3}{2} = - \frac{1}{2} = -0.5 \]

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