(-1,56-1,24)×(-1 10/28) = 3 4/5
1) -1.56 -1.24 = -(1,56+1,24) = -2.8
2) -2 8/10 * -1 10/28 = - 28/10 * - 38/28 = 19/5 = 3 4/5
(4 10/18-3 14/24):(-1 16/54)= -3/4
1) 4 10/18- 3 14/24 = 4 40/72 - 3 42/72 = 3 112/72 - 3 42/72 = 70/72 = 35/36
2) 35/36: -1 16/54 = 35/36 : -70/54 = 35/36* - 54/70= - 3/4
ответ: 3 4/5 ; -3/4
