Answer 1

$\frac{1}{5} \div \frac{3}{25} \div \frac{35}{12} = \frac{1}{5} \times \frac{25}{3} \div \frac{35}{12} = \frac{5 }{3} \times \frac{12}{35} = \frac{4}{7}$
$\frac{15}{36} \div \frac{3}{4} \div \frac{5}{16} = \frac{15}{36} \times \frac{4}{3} \div \frac{5}{16} = \frac{5}{9} \times \frac{16}{5} = \frac{16}{9}$
$\frac{10}{7} \div \frac{19}{6} \div \frac{18}{38} = \frac{10}{7} \times \frac{6}{19} \div \frac{18}{38} = \frac{60}{133} \times \frac{38}{18} = \frac{20}{21}$
$\frac{5}{8} \div \frac{9}{24} \div \frac{20}{18} = \frac{5}{8} \times \frac{24}{9} \div \frac{20}{18} = \frac{5}{3} \times \frac{18}{20} = \frac{3}{2}$
