\[ \frac{4}{4} - \frac{6}{8} = \frac{1}{4} = 0.25 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{4}{4}\) and \(\frac{-6}{8}\) is \(8\). \[ \begin{aligned} \frac{4}{4} - \frac{6}{8} &= \frac{4 \cdot 2}{4 \cdot 2} + \frac{-6 \cdot 1}{8 \cdot 1} \\ &= \frac{8 + -6}{8} \\ &= \frac{2}{8} \\&= \frac{1}{4} \end{aligned} \]
