Практика: Сокращение дробей

1. \( \frac{3}{63} = \frac{3:3}{63:3} = \frac{1}{21} \)
2. \( \frac{8}{10} = \frac{8:2}{10:2} = \frac{4}{5} \)
3. \( \frac{4}{96} = \frac{4:4}{96:4} = \frac{1}{24} \)
4. \( \frac{10}{25} = \frac{10:5}{25:5} = \frac{2}{5} \)
5. \( \frac{14}{16} = \frac{14:2}{16:2} = \frac{7}{8} \)
6. \( \frac{7}{84} = \frac{7:7}{84:7} = \frac{1}{12} \)
7. \( \frac{28}{32} = \frac{28:4}{32:4} = \frac{7}{8} \)
8. \( \frac{12}{30} = \frac{12:6}{30:6} = \frac{2}{5} \)
9. \( \frac{26}{30} = \frac{26:2}{30:2} = \frac{13}{15} \)
10. \( \frac{18}{24} = \frac{18:6}{24:6} = \frac{3}{4} \)
11. \( \frac{25}{75} = \frac{25:25}{75:25} = \frac{1}{3} \)
12. \( \frac{42}{126} = \frac{42:42}{126:42} = \frac{1}{3} \)
13. \( \frac{33}{77} = \frac{33:11}{77:11} = \frac{3}{7} \)
14. \( \frac{35}{84} = \frac{35:7}{84:7} = \frac{5}{12} \)
15. \( \frac{48}{72} = \frac{48:24}{72:24} = \frac{2}{3} \)
16. \( \frac{34}{50} = \frac{34:2}{50:2} = \frac{17}{25} \)
17. \( \frac{15}{63} = \frac{15:3}{63:3} = \frac{5}{21} \)
18. \( \frac{16}{20} = \frac{16:4}{20:4} = \frac{4}{5} \)
