Answer 1

Respuesta:

$-\frac{7}{6}\:+\:\left[\frac{3}{8}-\:\left(-\:\frac{5}{9}\right)\right]-\:\left[\frac{5}{3}\::\:\left(-\:\frac{4}{7}\right)\right]=\\\\\\=-\frac{7}{6}+\frac{67}{72}-\left[\frac{5}{3}\div \left(-\frac{4}{7}\right)\right]\\\\=-\frac{7}{6}+\frac{67}{72}-\left(-\frac{35}{12}\right)\\\\=\frac{193}{72}\\\\=2\frac{49}{72}$
