а) 5 : 4, 9 : 7, 10 : 3, 33 : 10;
б) 6 : 8, 14 : 21, 9 : 21, 20 : 50;
в) 12 : 9, 20 : 16, 15 : 10, 90 : 50.
$5 : 4 = \frac{5}{4} = 1\frac{1}{4}$;
$9 : 7 = \frac{9}{7} = 1\frac{2}{7}$;
$10 : 3 = \frac{10}{3} = 3\frac{1}{3}$;
$33 : 10 = \frac{33}{10} = 3\frac{3}{10}$.
$6 : 8 = \frac{6}{8} = \frac{3}{4}$;
$14 : 21 = \frac{14}{21} = \frac{2}{3}$;
$9 : 21 = \frac{9}{21} = \frac{3}{7}$;
$20 : 50 = \frac{20}{50} = \frac{2}{5}$.
$12 : 9 = \frac{12}{9} = \frac{4}{3} = 1\frac{1}{3}$;
$20 : 16 = \frac{20}{16} = \frac{5}{4} = 1\frac{1}{4}$;
$15 : 10 = \frac{15}{10} = \frac{3}{2} = 1\frac{1}{2}$;
$90 : 50 = \frac{90}{50} = \frac{9}{5} = 1\frac{4}{5}$.
