Сокращение дробей 35. Сократите дробь: 1) \( \frac{6}{4} \) 2) \( \frac{7}{28} \) 3) \( \frac{6}{20} \) 4) \( \frac{24}{56} \) 5) \( \frac{42}{98} \) 6) \( \frac{18}{81} \) 7) \( \frac{60}{156} \) 8) \( \frac{300}{450} \)

Решение:

1. \( \frac{6}{4} = \frac{6:2}{4:2} = \frac{3}{2} \)
2. \( \frac{7}{28} = \frac{7:7}{28:7} = \frac{1}{4} \)
3. \( \frac{6}{20} = \frac{6:2}{20:2} = \frac{3}{10} \)
4. \( \frac{24}{56} = \frac{24:8}{56:8} = \frac{3}{7} \)
5. \( \frac{42}{98} = \frac{42:14}{98:14} = \frac{3}{7} \)
6. \( \frac{18}{81} = \frac{18:9}{81:9} = \frac{2}{9} \)
7. \( \frac{60}{156} = \frac{60:12}{156:12} = \frac{5}{13} \)
8. \( \frac{300}{450} = \frac{300:150}{450:150} = \frac{2}{3} \)

Ответ: 1) \( \frac{3}{2} \); 2) \( \frac{1}{4} \); 3) \( \frac{3}{10} \); 4) \( \frac{3}{7} \); 5) \( \frac{3}{7} \); 6) \( \frac{2}{9} \); 7) \( \frac{5}{13} \); 8) \( \frac{2}{3} \).
