Сокращение дробей

1. а) $$ \frac{120}{224} = \frac{120:8}{224:8} = \frac{15}{28}$$
2. б) $$ \frac{264}{1540} = \frac{264:4}{1540:4} = \frac{66}{385} = \frac{66:11}{385:11} = \frac{6}{35}$$
3. в) $$ \frac{4050}{486} = \frac{4050:2}{486:2} = \frac{2025}{243} = \frac{2025:9}{243:9} = \frac{225}{27} = \frac{225:9}{27:9} = \frac{25}{3} = 8\frac{1}{3}$$
4. г) $$ \frac{4455}{4725} = \frac{4455:5}{4725:5} = \frac{891}{945} = \frac{891:9}{945:9} = \frac{99}{105} = \frac{99:3}{105:3} = \frac{33}{35}$$

Ответ: а) $$\frac{15}{28}$$; б) $$\frac{6}{35}$$; в) $$8\frac{1}{3}$$; г) $$\frac{33}{35}$$
