Пошаговое объяснение:
1) 10 - 14. 5/7 = -4. 5/7
2) -21/22 * (-4. 5/7) =
-21/22 * (-33/7) = -3/2 * (-3/1) = 9/2 = 4. 1/2
3) 8. 10/17 - 10 =
8. 10/17 - 9. 17/17 = -1. 7/17
4) 48 : (-1. 7/17) = 48 : (-24/17) = 48 * (-17/24) = 2 * (-17/1) = -34/1 = -34
5) 4. 1/2 + (-34) =
4. 1/2 - 34 = 4. 1/2 - 33. 2/2 = -29. 1/2
