Answer 2

$\frac{1}{9} \div 3 = \frac{1}{9} \times \frac{1}{3} = \frac{1}{27} \\ \\ \frac{3}{5} \div 3 = \frac{3}{5} \times \frac{1}{3} = \frac{1}{5} \\ \\ \frac{3}{2} \div 3 = \frac{3}{2} \times \frac{1}{3} = \frac{1}{2} \\ \\ \frac{5}{7} \div 3 = \frac{5}{7} \times \frac{1}{3} = \frac{5}{21} \\ \\ \frac{1}{9} \div \frac{1}{3} = \frac{1}{9} \times 3 = \frac{1}{3} \\ \\ \frac{3}{5} \div \frac{1}{3} = \frac{3}{5} \times 3 = \frac{9}{5} = 1 \frac{4}{5} \\ \\ \frac{3}{2} \div \frac{1}{3} = \frac{3}{2} \times 3 = \frac{9}{2} = 4 \frac{1}{2} \\ \\ \frac{5}{7} \div \frac{1}{3} = \frac{5}{7} \times 3 = \frac{15}{7} = 2 \frac{1}{7}$
