\(\frac{59}{10}\div\frac{2}{3}-\left(\frac{7}{3}.\frac{9}{2}-2.\frac{7}{3}\right)\div\frac{7}{4}\)
\(=\frac{59}{10}.\frac{3}{2}-\left(\frac{7}{3}.\frac{9}{2}-2.\frac{7}{3}\right).\frac{4}{7}\)
\(=\frac{177}{20}-\left(\frac{21}{2}-\frac{14}{3}\right).\frac{4}{7}\)
\(=\frac{177}{20}-\frac{35}{6}.\frac{4}{7}\)
\(=\frac{177}{20}-\frac{70}{21}\)
\(=\frac{ }{ }\)
