Решите задачу:

$1 \frac{7}{8} \div 4 \frac{1}{6} = \frac{15}{8} \div \frac{25}{6} = \frac{15}{8} \times \frac{6}{15} = \frac{9}{20} \\ \\ 6 \frac{2}{3} \div 2 \frac{7}{9} = \frac{20}{3} \div \frac{25}{9} = \frac{20}{3} \times \frac{9}{20} = \frac{12}{5} = 2 \frac{2}{4} \\ \\ 5 \frac{1}{3} \div 3\frac{5}{9} = \frac{16}{3} \div \frac{32}{9} = \frac{16}{3} \times \frac{9}{32} = \frac{3}{2} = 1 \frac{1}{2} \\ \\ 5 \frac{5}{14} \div 2 \frac{1}{7} = \frac{75}{14} \div \frac{15}{7} = \frac{75}{14} \times \frac{7}{15} = \frac{5}{2} = 2 \frac{1}{2} \\ \\ 6 \frac{2}{5} \div 1 \frac{7}{9} = \frac{32}{5} \div \frac{16}{9} = \frac{32}{5} \times \frac{9}{16} = \frac{2}{5} \times 9 = \frac{18}{5} = 3 \frac{3}{5}$
