Answer 2

Находим НОЗ:

$\frac{7}{25} и \frac{4}{15} = \frac{21}{75} и \frac{20}{75}$

$\frac{3}{10} и \frac{1}{6} = \frac{9}{30} и \frac{5}{30}$

$\frac{2}{5} и \frac{11}{30} = \frac{12}{30} и \frac{11}{30}$

$\frac{3}{8} и \frac{7}{20} = \frac{15}{40} и \frac{14}{40}$

$\frac{1}{6} и \frac{1}{7} = \frac{7}{42} и \frac{6}{42}$

$\frac{5}{9} и \frac{7}{15} = \frac{25}{45} и \frac{21}{45}$

$\frac{3}{8} и \frac{19}{56} = \frac{21}{56} и \frac{19}{56}$

$\frac{1}{4} и \frac{1}{8} = \frac{2}{8} и \frac{1}{8}$

$\frac{11}{4} и \frac{8}{21} = \frac{231}{84} и \frac{32}{84}$

$\frac{19}{45} и \frac{7}{18} = \frac{38}{90} и \frac{35}{90}$
