Answer 2

$\frac{5}{9}:\frac{3}{4}=\frac{5}{9}\cdot\frac{4}{3}=\frac{20}{27}\\\frac{1}{6}:\frac{2}{5}=\frac{1}{6}:\frac{5}{2}=\frac{5}{12}\\\frac{7}{12}:\frac{1}{5}=\frac{1}{3}\cdot5=\frac{5}{3}\\\frac{1}{8}:\frac{1}{4}=\frac{1}{8}\cdot4=\frac{1}{2}\\\frac{1}{5}:\frac{1}{25}=\frac{1}{5}\cdot25=5\\ \frac{3}{10}:\frac{1}{100}=\frac{3}{10}\cdot100=3\cdot10=30$
