​

Answer 1

Respuesta:

$\frac{ - 9}{2}$

Explicación paso a paso:

$- 3( \frac{1}{2} + 1 - \frac{5}{6} ) + (( - 2(3 - \frac{5}{4} ) + 1) \\ - 3( \frac{1}{2} + \frac{2}{2} - \frac{5}{6} ) + (( - 2( \frac{12}{4} - \frac{5}{4} )) + 1 \\ - 3( \frac{9}{6} - \frac{5}{6} ) + ( - 2( \frac{7}{4} ) + 1) \\ - 3 \times \frac{4}{6} + ( \frac{ - 14}{4} + 1) \\ \frac{ - 12}{6} + ( \frac{ - 14}{4} + \frac{4}{4} ) \\ \frac{ - 12}{6} + \frac{ - 10}{4} = \frac{ - 6}{3} + \frac{ - 5}{2} = \\ \frac{ - 27}{6} = \frac{ - 9}{2}$
