1) $\frac{5}{9} + \frac{4}{9} * 3\frac{1}{6} * (\frac{4}{19} + 1\frac{5}{38} - \frac{75}{76})$;
2) $(1\frac{5}{54} - \frac{11}{36}) * 3\frac{3}{5} * 2\frac{2}{7} - 1\frac{2}{7} * 1\frac{5}{9}$.
$\frac{5}{9} + \frac{4}{9} * 3\frac{1}{6} * (\frac{4}{19} + 1\frac{5}{38} - \frac{75}{76}) = \frac{5}{9} + \frac{4}{9} * \frac{19}{6} * (\frac{16}{76} + \frac{86}{76} - \frac{75}{76}) = \frac{5}{9} + \frac{4}{9} * \frac{19}{6} * \frac{27}{76} = \frac{5}{9} + \frac{1}{1} * \frac{1}{2} * \frac{1}{1} = \frac{5}{9} + \frac{1}{2} = \frac{10}{18} + \frac{9}{18} = \frac{19}{18} = 1\frac{1}{18}$
$(1\frac{5}{54} - \frac{11}{36}) * 3\frac{3}{5} * 2\frac{2}{7} - 1\frac{2}{7} * 1\frac{5}{9} = (\frac{118}{108} - \frac{33}{108}) * \frac{18}{5} * \frac{16}{7} - \frac{9}{7} * \frac{14}{9} = \frac{85}{108} * \frac{18}{5} * \frac{16}{7} - \frac{1}{1} * \frac{2}{1} = \frac{17}{3} * \frac{1}{1} * \frac{8}{7} - 2 = \frac{136}{21} - 2 = 6\frac{10}{21} - 2 = 4\frac{10}{21}$
