5.357 Сократите дроби: а) \( \frac{6}{10}, \frac{6}{18}, \frac{9}{15}, \frac{9}{24} \); б) \( \frac{2}{12}, \frac{3}{15}, \frac{30}{42} \)

а) \( \frac{6}{10} = \frac{3}{5} \); \( \frac{6}{18} = \frac{1}{3} \); \( \frac{9}{15} = \frac{3}{5} \); \( \frac{9}{24} = \frac{3}{8} \). б) \( \frac{2}{12} = \frac{1}{6} \); \( \frac{3}{15} = \frac{1}{5} \); \( \frac{30}{42} = \frac{5}{7} \). Ответ: а) \( \frac{3}{5}, \frac{1}{3}, \frac{3}{5}, \frac{3}{8} \); б) \( \frac{1}{6}, \frac{1}{5}, \frac{5}{7} \)
