СРОЧНО ДАЮ 30 БАЛЛОВ

8/30 + 4/30 + 6/30 = (8 + 4 + 6) / 30 = 18 / 30 = 3 / 5
64/70 - (5/70 + 26/70) = 64/70 - 31/70 = 33/70
34/60 + 8/60 + (41/60 - 16/60) = 42/60 = 7/10
10/15 + (14/15 - 4/15) = 10/15 + 10/15 = 20/15 = 4/3
(13/67 - 6/67) - 6/67 = 7/67 - 6/67 = 1/67
28/46 - (30/46 - 2/46) = 28/46 - 28/46 = 0.
