№2. Сократите дроби: 1) 12/16; 2) 120/150; 3) (9 · 16)/(4 · 27); 4) (12 · 15 · 21 · 3)/(5 · 42 · 30 · 24).

1) \(\frac{12}{16}=\frac{3}{4}\).

2) \(\frac{120}{150}=\frac{4}{5}\).

3) \(\frac{9\cdot16}{4\cdot27}=\frac{1\cdot4}{1\cdot3}=\frac{4}{3}=1\frac{1}{3}\).

4) \(\frac{12\cdot15\cdot21\cdot3}{5\cdot42\cdot30\cdot24}=\frac{1}{20}\).

Ответ: 1) \(\frac{3}{4}\); 2) \(\frac{4}{5}\); 3) \(\frac{4}{3}\); 4) \(\frac{1}{20}\).
