\[ \frac{7}{10} - \frac{1}{3} = \frac{11}{30} = 0.3\overline{6} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{7}{10}\) and \(\frac{-1}{3}\) is \(30\). \[ \begin{aligned} \frac{7}{10} - \frac{1}{3} &= \frac{7 \cdot 3}{10 \cdot 3} + \frac{-1 \cdot 10}{3 \cdot 10} \\ &= \frac{21 + -10}{30} \\ &= \frac{11}{30} \end{aligned} \]
