1) $\frac{5\frac{1}{7} * \frac{3}{5} : 3\frac{3}{5}}{12\frac{1}{4} : 1\frac{3}{4}}$;
2) $\frac{2\frac{2}{7} * 2,4 * 1\frac{5}{9} * 1\frac{9}{16}}{3\frac{1}{3} * 1,125 * 1\frac{5}{7} * 1\frac{7}{9}}$.
$\frac{5\frac{1}{7} * \frac{3}{5} : 3\frac{3}{5}}{12\frac{1}{4} : 1\frac{3}{4}} = \frac{\frac{36}{7} * \frac{3}{5} * \frac{5}{18}}{\frac{49}{4} * \frac{4}{7}} = \frac{\frac{2}{7} * \frac{3}{1} * \frac{1}{1}}{\frac{7}{1} * \frac{1}{1}} = \frac{\frac{6}{7}}{7} = \frac{6}{7} * \frac{1}{7} = \frac{6}{49}$
$\frac{2\frac{2}{7} * 2,4 * 1\frac{5}{9} * 1\frac{9}{16}}{3\frac{1}{3} * 1,125 * 1\frac{5}{7} * 1\frac{7}{9}} = \frac{\frac{16}{7} * \frac{12}{5} * \frac{14}{9} * \frac{25}{16}}{\frac{10}{3} * \frac{9}{8} * \frac{12}{7} * \frac{16}{9}} = \frac{\frac{1}{1} * \frac{4}{1} * \frac{2}{3} * \frac{5}{1}}{\frac{5}{1} * \frac{1}{1} * \frac{1}{7} * \frac{16}{1}} = \frac{40}{3} : \frac{80}{7} = \frac{40}{3} * \frac{7}{80} = \frac{1}{3} * \frac{7}{2} = \frac{7}{6} = 1\frac{1}{6}$
