Вариант №2. Сократите дробь: 1) \(\frac{6m}{18n}\); 2) \(\frac{14ab}{2af}\); 3) \(\frac{16p^3}{48p^3}\); 4) \(\frac{4mn^2q}{28m^2ny^3}\).

1. \(\frac{6m}{18n}=\frac{m}{3n}\).
2. \(\frac{14ab}{2af}=\frac{7b}{f}\).
3. \(\frac{16p^3}{48p^3}=\frac{1}{3}\).
4. \(\frac{4mn^2q}{28m^2ny^3}=\frac{nq}{7my^3}\).

Ответ: 1) \(\frac{m}{3n}\); 2) \(\frac{7b}{f}\); 3) \(\frac13\); 4) \(\frac{nq}{7my^3}\).
