Пошаговое объяснение:
1) -5/9 + 0,6 = -5/9 + 6/10 = -50/90 + 54/90 = 4/90 = 2/45
2) 2/45 * 3/8 = 1/15 * 1/4 = 1/60
3) 5/9 - 2,1 = 5/9 - 21/10 = 50/90 - 189/90 = -139/90
4) -139/90 * 2 2/3 = -139/90 * 8/3 = -139/45 * 4/3 = -556/135 = -4 16/135
5) 1/60 + (-4 16/135) = 1/60 - 4 16/135 = -443/108 = -4 11/108
