а)
Пошаговое объяснение:
А)
-4,8 + (2. 2/3 - (-5/6)) =
-4. 8/10 + (2. 2/3 + 5/6) =
-4. 4/5 + (2. 4/6 + 5/6) =
-4. 4/5 + 7. 9/6 = -4. 4/5 + 8. 3/6 =
-4. 24/30 + 8. 15/30 = -4. 24/30 +
7. 45/30 = 3. 21/30 = 3. 7/10
Б)
1) - 1/12 + 2/5 = -5/60 + 24/60 = 19/60
2) -0,36 - 0,64 = - 1
3) 19/60 - (-1) = 19/60 + 1 = 1. 19/60
4) 1. 19/60 - 1/15 = 1. 19/60 - 4/60 =
1. 15/60 = 1. 1/4
