$\frac{4}{18}; \frac{5}{18} \\\\ \frac{21}{35}; \frac{20}{35} \\\\ \frac{25}{70}; \frac{16}{70} \\\\ \frac{33}{216}; \frac{28}{216} \\$

$\frac{5}{16} \ \textgreater \ \frac{5}{21} \\\\ \frac{11}{20} = \frac{33}{60} \ \textgreater \ \frac{32}{60} = \frac{8}{15} \\\\ \frac{46}{213} \ \textless \ 1 \ \textless \ \frac{391}{264} \\\\ 0.32 = \frac{32}{100} \ \textless \ \frac{35}{100} = \frac{7}{20}$
