Ответ:

$1)5 \frac{1}{3} \times 2 \frac{1}{4} \div \frac{7}{5} = \frac{16}{3} \times \frac{9}{4} \div \frac{7}{5} = \frac{12}{1} \div \frac{7}{5} = \frac{12}{1} \times \frac{5}{7} = \frac{60}{7} = 8 \frac{4}{7} \\ 2)(2 \frac{1}{2} + 1 \frac{1}{3} ) \div \frac{1}{6} - 5 \frac{3}{7} = (3 \frac{2 + 3}{6} ) \div \frac{1}{6} - 5 \frac{3}{7} = 3 \frac{5}{6} \div \frac{1}{6} - 5 \frac{3}{7} = \frac{23}{6} \times \frac{6}{1} - 5 \frac{3}{7} = 23 - 5 \frac{3}{7} = 22 \frac{7}{7} - 5 \frac{3}{7} = 17 \frac{7 - 3}{7} = 17 \frac{4}{7}$
