\[ \frac{-1}{4} - \frac{3}{2} = - \frac{7}{4} = -1.75 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{-1}{4}\) and \(\frac{-3}{2}\) is \(4\). \[ \begin{aligned} \frac{-1}{4} - \frac{3}{2} &= \frac{-1 \cdot 1}{4 \cdot 1} + \frac{-3 \cdot 2}{2 \cdot 2} \\ &= \frac{-1 + -6}{4} \\ &= \frac{-7}{4} \end{aligned} \]
