\[ \frac{1}{2} - \frac{3}{5} = - \frac{1}{10} = -0.1 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{2}\) and \(\frac{-3}{5}\) is \(10\). \[ \begin{aligned} \frac{1}{2} - \frac{3}{5} &= \frac{1 \cdot 5}{2 \cdot 5} + \frac{-3 \cdot 2}{5 \cdot 2} \\ &= \frac{5 + -6}{10} \\ &= \frac{-1}{10} \end{aligned} \]
