\[ \frac{3}{5} + \frac{7}{110} = \frac{73}{110} = 0.6\overline{63} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{5}\) and \(\frac{7}{110}\) is \(110\). \[ \begin{aligned} \frac{3}{5} + \frac{7}{110} &= \frac{3 \cdot 22}{5 \cdot 22} + \frac{7 \cdot 1}{110 \cdot 1} \\ &= \frac{66 + 7}{110} \\ &= \frac{73}{110} \end{aligned} \]
