2) Сократите дроби: 2/8, 15/18, 7/28, 3/9, 14/34, 4/64, 18/48, 56/72, 3/87, 10/45, 2/38, 45/63, 5/35, 6/66

Решение:

2) Сокращение дробей:

• \( \frac{2}{8} = \frac{2:2}{8:2} = \frac{1}{4} \)
• \( \frac{15}{18} = \frac{15:3}{18:3} = \frac{5}{6} \)
• \( \frac{7}{28} = \frac{7:7}{28:7} = \frac{1}{4} \)
• \( \frac{3}{9} = \frac{3:3}{9:3} = \frac{1}{3} \)
• \( \frac{14}{34} = \frac{14:2}{34:2} = \frac{7}{17} \)
• \( \frac{4}{64} = \frac{4:4}{64:4} = \frac{1}{16} \)
• \( \frac{18}{48} = \frac{18:6}{48:6} = \frac{3}{8} \)
• \( \frac{56}{72} = \frac{56:8}{72:8} = \frac{7}{9} \)
• \( \frac{3}{87} = \frac{3:3}{87:3} = \frac{1}{29} \)
• \( \frac{10}{45} = \frac{10:5}{45:5} = \frac{2}{9} \)
• \( \frac{2}{38} = \frac{2:2}{38:2} = \frac{1}{19} \)
• \( \frac{45}{63} = \frac{45:9}{63:9} = \frac{5}{7} \)
• \( \frac{5}{35} = \frac{5:5}{35:5} = \frac{1}{7} \)
• \( \frac{6}{66} = \frac{6:6}{66:6} = \frac{1}{11} \)

Ответ: 1/4, 5/6, 1/4, 1/3, 7/17, 1/16, 3/8, 7/9, 1/29, 2/9, 1/19, 5/7, 1/7, 1/11.
