[tex]a. \frac{3}{5} \div \frac{6}{7} = \frac{3 \times 7}{5 \times 6} = \frac{7}{10 } \\ b. \frac{1}{6} \div \frac{7}{12} = \frac{1 \times 12}{6 \times 7} = \frac{2}{7} \\ c. \frac{1}{3} \div \frac{2}{9} = \frac{1 \times 9}{3 \times 2} = \frac{3}{2} = 1 \times \frac{1}{2} \\ d. \frac{1}{9 } \div \frac{1}{7} = \frac{7}{9} \\ e.7 \div \frac{7}{3} = \frac{7 \times 3}{7} = 3 \\ f. \frac{5}{8} \div \frac{2}{3} = \frac{5 \times 3}{8 \times 2} = \frac{15}{16} \\ g. \frac{7}{9} \div \frac{1}{3} = \frac{7 \times 3}{9 \times 1} = \frac{7}{3} = 2 \times \frac{1}{3} \\ h. \frac{5}{8} \div \frac{1}{2} = \frac{5 \times 2}{8 \times 1} = \frac{5}{4} = 1 \times \frac{1}{4} [/tex]
