Вычислите 3/4 от числа c при: 1) c = 2; 2) c = 1 1/3; 3) c = 2/9; 4) c = 1,6; 5) c = 5; 6) c = 6,4; 7) c = 3/16.

1. \(\frac{3}{4}\cdot2=\frac{3}{2}=1\frac{1}{2}\).
2. \(\frac{3}{4}\cdot1\frac{1}{3}=\frac{3}{4}\cdot\frac{4}{3}=1\).
3. \(\frac{3}{4}\cdot\frac{2}{9}=\frac{6}{36}=\frac{1}{6}\).
4. \(\frac{3}{4}\cdot1.6=1.2\).
5. \(\frac{3}{4}\cdot5=\frac{15}{4}=3\frac{3}{4}\).
6. \(\frac{3}{4}\cdot6.4=4.8\).
7. \(\frac{3}{4}\cdot\frac{3}{16}=\frac{9}{64}\).

Ответ: 1) \(1\frac{1}{2}\); 2) \(1\); 3) \(\frac{1}{6}\); 4) \(1,2\); 5) \(3\frac{3}{4}\); 6) \(4,8\); 7) \(\frac{9}{64}\).
