Приведите обыкновенные дроби 1 и 3 2 и 3 1 и 5 2 и 5 4 и 5 1 и 6 5 и 6 5 и 6 3 и 10 7 и...

Решите задачу:

$\frac{1}{3} = \frac{10}{30} \\ \frac{2}{3} = \frac{2 \times 10}{3 \times 10} = \frac{20}{30} \\ \frac{1}{5} = \frac{6}{5 \times 6} = \frac{6}{30} \\ \frac{2}{5} = \frac{12}{30} \\$
$\frac{4}{5} = \frac{24}{30} \\ \frac{1}{6} = \frac{5}{30} \\ \frac{5}{6} = \frac{25}{30} \\ \frac{3}{10} = \frac{9}{30} \\$
$\frac{7}{10} = \frac{21}{10} \\ \frac{9}{10} = \frac{27}{30}$
