Пошаговое объяснение:
(0,2 - 7/15) * (-5/8) - (-5/12 - 0,75) : 2 1/3 = 2/3
0,2 - 7/15 = 1/5 - 7/15 = (3-7) / 15 = - 4/15
- 4/15 * (-5/8) = 1/6
-5/12 - 0,75 = -15/12 - 3/4 = (-5-9) / 12 = - 14/12 = - 7/6
- 7/6 : 2 1/3 = -2 : 7/3 = - 7/6 * 3/7 = - 1/2
1/6 - (-1/2) = 2/3
-4 1/8 * (-2,5) * 1,6 = - 4,125 * (-2,5) * 1,6 = 16,5 = 33/2
0,5 * 2 1/4 * (- 8,8) = 0,5 * 2,25 * (-8,8) = -9,9 = -99/10
33/2 : (-99/10) = 33/2 * (-10/99) = -5/3 = - 1 2/3
