\[ \frac{1}{3} - \frac{11}{12} = - \frac{7}{12} = -0.58\overline{3} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{3}\) and \(\frac{-11}{12}\) is \(12\). \[ \begin{aligned} \frac{1}{3} - \frac{11}{12} &= \frac{1 \cdot 4}{3 \cdot 4} + \frac{-11 \cdot 1}{12 \cdot 1} \\ &= \frac{4 + -11}{12} \\ &= \frac{-7}{12} \end{aligned} \]
