Answer 1

$7 \frac{1}{3} \div \frac{2}{3} - 1 \frac{5}{6} \times (2 \frac{7}{9} - 4 \frac{1}{6} ) = \\ = \frac{22}{3} \div \frac{2}{3} - \frac{11}{6} \times ( \frac{25}{9} - \frac{25}{6} ) = \\ = \frac{22}{3} \div \frac{2}{3} - \frac{11}{6} \times ( \frac{150}{54} - \frac{225}{54} ) = \\ = \frac{22}{3} \div \frac{2}{3} - \frac{11}{6} \times ( - \frac{75}{54} ) = \\ = \frac{22}{3} \div \frac{2}{3} + \frac{275}{108} = \\ = \frac{22}{3} \times \frac{3}{2} + \frac{275}{108} = \\ = 11 + \frac{275}{108} = \\ = \frac{1188}{108} + \frac{275}{108} = \\ = \frac{1463}{108} = 13 \frac{59}{108}$
