1. Вычислите: 1) 14 − 5,841; 2) 3 5/12 + 14 11/12; 3) 3,5 · 20,8; 4) 14,892 : 7,3; 5) 4 1/4 − 2 3/4; 6) 3/8 : 7/12.

1. \(14 - 5.841 = 8.159\).
2. \(3\frac{5}{12}+14\frac{11}{12}=17+\frac{16}{12}=18\frac{1}{3}\).
3. \(3.5\cdot20.8=72.8\).
4. \(14.892:7.3=2.04\).
5. \(4\frac{1}{4}-2\frac{3}{4}=1\frac{1}{2}\).
6. \(\frac{3}{8}:\frac{7}{12}=\frac{3}{8}\cdot\frac{12}{7}=\frac{9}{14}\).

Ответ: 1) 8,159; 2) 18 1/3; 3) 72,8; 4) 2,04; 5) 1 1/2; 6) 9/14.
