Пошаговое объяснение:
a) = (1 + 2 + 1) + ( 5/7 + 3/7 + 4/7) = 4 + 12/7 = 5 5/7
б) = ( 13 + 5 - 2) + ( 4/7 + 5/7 - 6/7) = 16 + 3/7 = 16 3/7
в) = (5 + 4 - 3) + ( 1/5 + 4/5 - 3/5) = 6 + 2/5 = 6 2/5
г) = (7 + 2 - 8) + (11/16 + 5/16 - 7/16) = 1 + 9/16 = 1 9/16
д) = (24 - 12 - 2) - (4/15 + 3/15 - 1/15) = 10 - 6/15 = 9 9/15 = 9 3/5
e) = (8 - 1 - 2) - (4/5 + 3/5 - 2/5) = 5 - 5/5 = 5 - 1 = 4
