Сократить дробь - это значит разделить числитель и знаменатель на их общий делитель.

1. $$\frac{2}{14} = \frac{2:2}{14:2} = \frac{1}{7}$$
2. $$\frac{3}{18} = \frac{3:3}{18:3} = \frac{1}{6}$$
3. $$\frac{4}{24} = \frac{4:4}{24:4} = \frac{1}{6}$$
4. $$\frac{5}{45} = \frac{5:5}{45:5} = \frac{1}{9}$$
5. $$\frac{6}{36} = \frac{6:6}{36:6} = \frac{1}{6}$$
6. $$\frac{7}{42} = \frac{7:7}{42:7} = \frac{1}{6}$$
7. $$\frac{22}{99} = \frac{22:11}{99:11} = \frac{2}{9}$$
8. $$\frac{55}{88} = \frac{55:11}{88:11} = \frac{5}{8}$$
9. $$\frac{22}{66} = \frac{22:22}{66:22} = \frac{1}{3}$$
10. $$\frac{11}{99} = \frac{11:11}{99:11} = \frac{1}{9}$$
11. $$\frac{11}{121} = \frac{11:11}{121:11} = \frac{1}{11}$$
12. $$\frac{13}{39} = \frac{13:13}{39:13} = \frac{1}{3}$$
13. $$\frac{2}{120} = \frac{2:2}{120:2} = \frac{1}{60}$$
14. $$\frac{3}{99} = \frac{3:3}{99:3} = \frac{1}{33}$$
15. $$\frac{3}{27} = \frac{3:3}{27:3} = \frac{1}{9}$$
