\[ \frac{3}{2} - \frac{11}{10} = \frac{2}{5} = 0.4 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{2}\) and \(\frac{-11}{10}\) is \(10\). \[ \begin{aligned} \frac{3}{2} - \frac{11}{10} &= \frac{3 \cdot 5}{2 \cdot 5} + \frac{-11 \cdot 1}{10 \cdot 1} \\ &= \frac{15 + -11}{10} \\ &= \frac{4}{10} \\&= \frac{2}{5} \end{aligned} \]
