Explicación paso a paso:

$( \frac{-2}{5})^{2}. (\frac{1}{2} -1) -\frac{3}{2} :( \frac{-5}{4}) = \\\frac{4}{25} .(\frac{1-2}{2})-\frac{3}{2} : (\frac{-5}{4})= \\\frac{4}{25} .(\frac{-1}{2})-\frac{3}{2} : (\frac{-5}{4})=\\\frac{4.(-1)}{25.2} -\frac{3.4}{2.(-5)} =\\\frac{-4}{50} -\frac{12}{(-10)} = \frac{-4(-10)-50.12}{50.(-10)} =\\\frac{+40-600}{(-500)} \\\frac{-560}{-500} \\= \frac{28}{25} = 1,12$
