$\frac{1}{3} \div \frac{1}{9} = \frac{1}{3} \times \frac{9}{1} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{9}{3} = 3$

$\frac{2}{5} \div \frac{3}{25} = \frac{2}{5} \times \frac{25}{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{50}{15} = 3\frac{5}{15}$

$\frac{4}{7} \div \frac{5}{9} = \frac{4}{7} \times \frac{9}{5} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:= \frac{36}{35} = 1 \frac{1}{35}$

$\frac{7}{12} \div \frac{3}{8} = \frac{7}{12} \times \frac{8}{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{56}{36} =1 \frac{20}{36}$
