[tex] \frac{1}{4} \div \frac{1}{5} = \frac{1}{4} \times \frac{5}{1} = \frac{5}{4} = 1 \frac{1}{4} \\ \\ \frac{3}{7} \div \frac{2}{5} = \frac{3}{7} \times \frac{5}{2} = \frac{15}{14} = 1 \frac{1}{14} \\ \\ \frac{2}{3} \div \frac{5}{6} = \frac{2}{3} \times \frac{6}{5} = \frac{12}{15} = \frac{4}{5} \\ \\ \frac{3}{7} \div \frac{9}{28} = \frac{3}{7} \times \frac{28}{9} = \frac{1}{1} \times \frac{4}{3} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
