Карточка №33. Сократите дроби

• \[\frac{6}{9} = \frac{6:3}{9:3} = \frac{2}{3}\]
• \[\frac{8}{24} = \frac{8:8}{24:8} = \frac{1}{3}\]
• \[\frac{4}{12} = \frac{4:4}{12:4} = \frac{1}{3}\]
• \[\frac{24}{60} = \frac{24:12}{60:12} = \frac{2}{5}\]
• \[\frac{14}{21} = \frac{14:7}{21:7} = \frac{2}{3}\]
• \[\frac{28}{42} = \frac{28:14}{42:14} = \frac{2}{3}\]
• \[\frac{8}{12} = \frac{8:4}{12:4} = \frac{2}{3}\]
• \[\frac{35}{42} = \frac{35:7}{42:7} = \frac{5}{6}\]
• \[\frac{9\cdot14}{28\cdot3} = \frac{3\cdot3\cdot2\cdot7}{4\cdot7\cdot3} = \frac{6}{4} = \frac{3}{2}\]
• \[\frac{39\cdot4}{8\cdot13} = \frac{3\cdot13\cdot4}{8\cdot13} = \frac{3\cdot4}{8} = \frac{3}{2}\]
