\[ \frac{2}{7} + \frac{6}{10} = \frac{31}{35} = 0.8\overline{857142} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{7}\) and \(\frac{6}{10}\) is \(70\). \[ \begin{aligned} \frac{2}{7} + \frac{6}{10} &= \frac{2 \cdot 10}{7 \cdot 10} + \frac{6 \cdot 7}{10 \cdot 7} \\ &= \frac{20 + 42}{70} \\ &= \frac{62}{70} \\&= \frac{31}{35} \end{aligned} \]
