| А | $\frac{2}{9} * \frac{4}{7} = \frac{2 * 4}{9 * 7} = \frac{8}{63}$ |
|---|---|
| К | $\frac{3}{8} * \frac{5}{6} = \frac{3 * 5}{8 * 6} = \frac{1 * 5}{8 * 2} = \frac{5}{16}$ |
| С | $\frac{14}{15} * \frac{3}{7} = \frac{14 * 3}{15 * 7} = \frac{2 * 1}{5 * 1} = \frac{2}{5}$ |
| В | $\frac{18}{55} * \frac{11}{18} = \frac{18 * 11}{55 * 18} = \frac{1 * 1}{5 * 1} = \frac{1}{5}$ |
| Л | $\frac{21}{32} * \frac{12}{35} = \frac{21 * 12}{32 * 35} = \frac{3 * 3}{8 * 5} = \frac{9}{40}$ |
| О | $\frac{19}{40} * \frac{8}{57} = \frac{19 * 8}{40 * 57} = \frac{1 * 1}{5 * 3} = \frac{1}{15}$ |
| Я | $\frac{15}{22} * \frac{4}{27} = \frac{15 * 4}{22 * 27} = \frac{5 * 2}{11 * 9} = \frac{10}{99}$ |
| Е | $\frac{41}{54} * \frac{63}{82} = \frac{41 * 63}{54 * 82} = \frac{1 * 7}{6 * 2} = \frac{7}{12}$ |
| $\frac{5}{16}$ | $\frac{1}{15}$ | $\frac{1}{5}$ | $\frac{8}{63}$ | $\frac{9}{40}$ | $\frac{7}{12}$ | $\frac{1}{5}$ | $\frac{2}{5}$ | $\frac{5}{16}$ | $\frac{8}{63}$ | $\frac{10}{99}$ |
