Answer 1

$\frac{16}{4} : 2 = \frac{16.1}{4.2} = \frac{16}{8} = \frac{2}{1} = 2$

$\frac{21}{9} : \frac{7}{3} = \frac{21.3}{9.7} = \frac{63}{63} = 1$

$\frac{16}{18} : \frac{4}{9} = \frac{16.9}{18.4} = \frac{144}{72} = \frac{2}{1} = 2$

$\frac{3}{7} : \frac{4}{5} = \frac{3.5}{7.4} = \frac{15}{28}$

$\frac{33}{4} : \frac{3}{4} = \frac{33.4}{4.3} = \frac{132}{12} = \frac{11}{1} = 11$

$\frac{40}{5} : \frac{20}{10} = \frac{40.10}{5.20} = \frac{400}{100} = \frac{4}{1} = 4$

$\frac{25}{2} : \frac{1}{4} = \frac{25.4}{2.1} = \frac{100}{2} = \frac{50}{1} = 50$

$80 \frac{1}{2} : 5 \frac{1}{12} = \\ \frac{80.2+1}{2} : \frac{5.12+1}{12} = \\ \frac{161}{2} : \frac{61}{12} = \frac{161.12}{2.61} = \frac{1932}{122}$

$5 : \frac{3}{5} = \frac{5.5}{1.3} = \frac{25}{3}$

$3 \frac{3}{4} : \frac{5}{2} = \\ \frac{3.4+3}{4} : \frac{5}{2} = \\ \frac{15}{4} : \frac{5}{2} = \frac{15.2}{4.5} = \frac{30}{20} = \frac{6}{4} = \frac{3}{2}$
