\[ \frac{3}{5} + \frac{7}{10} + \frac{1}{2} = \frac{9}{5} = 1.8 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{5}\), \(\frac{7}{10}\), and \(\frac{1}{2}\) is \(10\). \[ \begin{aligned} \frac{3}{5} + \frac{7}{10} + \frac{1}{2} &= \frac{3 \cdot 2}{5 \cdot 2} + \frac{7 \cdot 1}{10 \cdot 1} + \frac{1 \cdot 5}{2 \cdot 5} \\ &= \frac{6 + 7 + 5}{10} \\ &= \frac{18}{10} \\&= \frac{9}{5} \end{aligned} \]
