Answer 1

$\frac{9}{4} \div \frac{1}{2} = \frac{9 \times 2}{4 \times 1} = \frac{18}{4} \\ \frac{7}{8} \div \frac{3}{5} = \frac{7 \times 5}{8 \times 3} = \frac{35}{24}$

$\frac{12}{7} \div \frac{2}{9} = \frac{12 \times 9}{7 \times 2} = \frac{108}{14} \\ \frac{9}{7} \div \frac{6}{5} = \frac{9 \times 5}{7 \times 6} = \frac{45}{42}$
