\[ \frac{3}{5} + \frac{2}{3} - \frac{1}{2} = \frac{23}{30} = 0.7\overline{6} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{5}\), \(\frac{2}{3}\), and \(\frac{-1}{2}\) is \(30\). \[ \begin{aligned} \frac{3}{5} + \frac{2}{3} - \frac{1}{2} &= \frac{3 \cdot 6}{5 \cdot 6} + \frac{2 \cdot 10}{3 \cdot 10} + \frac{-1 \cdot 15}{2 \cdot 15} \\ &= \frac{18 + 20 + -15}{30} \\ &= \frac{23}{30} \end{aligned} \]
