\[ \frac{5}{3} - \frac{2}{1} = - \frac{1}{3} = -0.\overline{3} \]

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