\[ \frac{3}{5} - \frac{3}{10} = \frac{3}{10} = 0.3 \]

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