Ответ:
1. 31 2. -3,6 3. 0,99 4. -24,85 5. 6 1/7 6. 8 17/24
Пошаговое объяснение:
1. -53+61-48+71 = 132 - 101 = 31
2. 3,17-5,9-0,87 = 3,17 - 6,77 = -3,6
3. -0,96+(-5,37)-(-1,02)+6,3 = -0,96 - 5,37 + 1,02 + 6,3 = -6,33+7,32 = 0,99
4. -19,23-15,88-(-21,34)+(-11,08) = -19,23-15,88+21,34-11,08 =
-46,19+21,34 = -24,85
5. 5 3/7 + (-2 2/3) - (-3 8/21) = 5 9/21-2 14/21+3 8/21 =
8 17/21-2 14/21 = 6 3/21 = 6 1/7
6. 2 5/6+(-3 1/8)-(-2 7/12)+4 3/4-(-1 2/3) =
2 20/24-3 3/24+2 14/24+4 18/24+1 16/24 =
9 68/24 - 3 3/24 = 11 20/24 - 3 3/24 = 8 17/24
