Вычислите: 1) 27/(3·4·5); 2) 16/(3·2·2); 3) 36/(4·4·5).

1. \(\frac{27}{3\cdot4\cdot5}=\frac{27}{60}=\frac{9}{20}\).
2. \(\frac{16}{3\cdot2\cdot2}=\frac{16}{12}=\frac{4}{3}\).
3. \(\frac{36}{4\cdot4\cdot5}=\frac{36}{80}=\frac{9}{20}\).

Ответ: 1) \(\frac{9}{20}\); 2) \(\frac{4}{3}\); 3) \(\frac{9}{20}\).
