Ответ:
1. 1 7/162
2. 4/27
3. -5
Пошаговое объяснение:
1) 1 1/12 : 1 1/26 = 13/12 * 26/27 = 169/162 = 1 7/162
2) 27/250 : 0,729 = 27/250 : 729/1000 = 27/750 * 1000/729 = 4/27
3) ((4 + 1/(1/2-1/3)) : ((4 - 1/(1/2 - 1/3)) = -5
По действиям:
1. 4 + 1/(1/2-1/3) = 4 + 1:1/6 = 4 + 1 * 6/1 = 4 + 6 = 10
2. 4 - 1/(1/2-1/3) = 4 - 1:1/6 = 4 - 1 * 6/1 = 4 - 6 = -2
3. 10 : (-2) = -5
