Answer 1

$\dfrac{3}{8} \div \dfrac{2}{3} = \dfrac{3}{8} \times \dfrac{3}{2} = \dfrac{9}{16}\\\\\dfrac{5}{16} \div \dfrac{1}{3} = \dfrac{5}{16} \times \dfrac{3}{1} = \dfrac{15}{16}\\\\3\dfrac{5}{9} \div 2\dfrac{2}{3} = \dfrac{32}{9} \div \dfrac{8}{3} = \dfrac{32}{9} \times \dfrac{3}{8} = \dfrac{4}{3} = 1\dfrac{1}{3}\\\\3\dfrac{1}{3} \div 2\dfrac{6}{7} = \dfrac{10}{3} \div \dfrac{20}{7} = \dfrac{10}{3} \div \dfrac{7}{20} = \dfrac{7}{6} = 1\dfrac{1}{6}$
