Answer 1

$\frac{3}{9 } \div \frac{4}{8} = \frac{3}{9} \times \frac{8}{4} = \frac{24}{36}$
$\frac{6}{7} \div \frac{5}{3} = \frac{6}{7} \times \frac{3}{5} = \frac{18}{35}$
$\frac{2}{5} \div \frac{8}{5} = \frac{2}{5} \times \frac{5}{8} = \frac{10}{40}$
$\frac{2}{4} \div \frac{3}{7} = \frac{2}{4} \times \frac{7}{3} = \frac{14}{12}$
$\frac{3}{8} \div \frac{4}{16} = \frac{3}{8} \times \frac{16}{4} = \frac{48}{32}$
$\frac{5}{7} \div \frac{9}{3} = \frac{5}{7} \times \frac{9}{3} = \frac{45}{21}$


$\frac{5} \div \frac{8}{9} = \frac{5}{1} \times \frac{9}{8} = \frac{45}{8}$
