\[ \frac{1}{-50} - \frac{1}{-25} = \frac{1}{50} = 0.02 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{-50}\) and \(\frac{-1}{-25}\) is \(50\). \[ \begin{aligned} \frac{1}{-50} - \frac{1}{-25} &= \frac{1 \cdot -1}{-50 \cdot -1} + \frac{-1 \cdot -2}{-25 \cdot -2} \\ &= \frac{-1 + 2}{50} \\ &= \frac{1}{50} \end{aligned} \]
