Пошаговое объяснение:
1) 1,134 : 0,28 = 4,05
2) 4,05 - 4,254 = -0,204
3) 2/3 * (-0,204) =
2/3 * (-204/1000) =
2/3 * (-51/250) = 1/1 * (-17/125) = -17/125 = -0,136
4) 4. 15/49 - 2. 13/14 =
4. 30/98 - 2. 91/98 =
3. 128/98 - 2. 91/98 =
1. 37/98
5) 1. 32/49 : 1. 37/98 =
81/49 : 135/98 = 81/49 * 98/135 = 3/1 * 2/5 = 6/5 =
1,2
6) -1,114 + (-0,136) =
-1,114 - 0,136 = -1,25
7) -1,25 + 1,2 = -0,05
Ответ: -0,05 или -1/20
