Ответ:
5. 3/10
Пошаговое объяснение:
1) 8 - 6. 1/4 = 7. 4/4 - 6. 1/4 = 1. 3/4
2) 1. 3/4 : (-5/8) = 7/4 : (-5/8) = 7/4 * (-8/5) = -56/20 = -14/5 = -2. 4/5
3) -1/2 - 2/5 = -5/10 - 4/10 = -9/10
4) 9 * (-9/10) = -81/10 = -8. 1/10
5) -2. 4/5 - (-8. 1/10) =
-2. 4/5 + 8. 1/10 =
-2. 8/10 + 8. 1/10 =
-2. 8/10 + 7. 11/10 =
