Answer 1

Respuesta:

$\left[\begin{array}{ccc}(\frac{2}{3}-\frac{1}{2}:\frac{3}{4} ):(\frac{5}{2}-\frac{3}{4} )-(\frac{9}{2} +\frac{1}{5} )\end{array}\right] }: (\frac{2}{3} -\frac{5}{2} )+\left[\begin{array}{ccc}(\frac{3}{4} -\frac{5}{6} ).\frac{4}{7}-\frac{25}{42} \end{array}\right]$

$\left[\begin{array}{ccc}(\frac{2}{3}-\frac{2}{3}):(\frac{7}{4} )-(\frac{47}{10} )\end{array}\right] }: (-\frac{11}{6} )+\left[\begin{array}{ccc}(-\frac{1}{12}).\frac{4}{7}-\frac{25}{42} \end{array}\right]$

$\left[\begin{array}{ccc}0:(\frac{7}{4} )-(\frac{47}{10} )\end{array}\right] }: (-\frac{11}{6} )+\left[\begin{array}{ccc}-\frac{1}{21}-\frac{25}{42} \end{array}\right]$

$\left[\begin{array}{ccc}0-\frac{47}{10} \end{array}\right] }: (-\frac{11}{6} )+\left[\begin{array}{ccc}-\frac{9}{14} \end{array}\right]$

$\left[\begin{array}{ccc}-\frac{47}{10} \end{array}\right] }: (-\frac{11}{6} )+\left[\begin{array}{ccc}-\frac{9}{14} \end{array}\right]$

$\frac{141}{55} +(-\frac{67}{42})$

$\frac{1479}{770}$
