\[ 2 - \frac{5}{4} = \frac{3}{4} = 0.75 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{1}\) and \(\frac{-5}{4}\) is \(4\). \[ \begin{aligned} 2 - \frac{5}{4} &= \frac{2 \cdot 4}{1 \cdot 4} + \frac{-5 \cdot 1}{4 \cdot 1} \\ &= \frac{8 + -5}{4} \\ &= \frac{3}{4} \end{aligned} \]
