\[ \frac{1}{25} - \frac{1}{100} = \frac{3}{100} = 0.03 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{25}\) and \(\frac{-1}{100}\) is \(100\). \[ \begin{aligned} \frac{1}{25} - \frac{1}{100} &= \frac{1 \cdot 4}{25 \cdot 4} + \frac{-1 \cdot 1}{100 \cdot 1} \\ &= \frac{4 + -1}{100} \\ &= \frac{3}{100} \end{aligned} \]
