Explicación paso a paso:
[tex] \frac{5}{6} \times 0.416 - 0.25 \times (2 - \frac{5}{4} = \\ \frac{5}{6} \times \frac{0.416}{1} - 0.25 \times ( \frac{8}{4} - \frac{5}{4} ) = \\ \frac{2.08}{6} - 0.25 \times \frac{3}{4} = \\ \frac{2.08}{6} - \frac{0.75}{4} = \\ \frac{4.16}{12} - \frac{2.25}{12} = 1.91 = 0.16[/tex]
