1. Вычислите: 1) 26 − 7,586; 2) 15 12/15 + 7 8/15; 3) 3,05 · 5,6; 4) 175,16 : 5,8; 5) 7 3/5 − 4 4/5; 6) 22/7 · 3/11.

1. \(26-7,586=18,414\).
2. \(15\frac{12}{15}+7\frac{8}{15}=22\frac{20}{15}=23\frac{1}{3}\).
3. \(3,05\cdot5,6=17,08\).
4. \(175,16:5,8=30,2\).
5. \(7\frac{3}{5}-4\frac{4}{5}=2\frac{4}{5}\).
6. \(\frac{22}{7}\cdot\frac{3}{11}=\frac{6}{7}\).

Ответ: 1) 18,414; 2) 23 1/3; 3) 17,08; 4) 30,2; 5) 2 4/5; 6) 6/7.
