д)6 3/7-5 5/7 =1 3/7- 5/7= 10/7-5/7=5/7
е)2 3/8-1 7/8 =1 3/8- 7/8= 11/8-7/8=4/8=1/2

Answer 2

a) 5 + 1/6 - 5/6 = 5 + (1/6 - 5/6) = 5 + (-4/6) = 5 - 2/3 = 15/3 - 2/3 = 13/3

б) 2 + 1/3 - 2/3 = 2 + (1/3 - 2/3) = 2 + (-1/3) = 2 - 1/3 = 6/3 - 1/3 = 5/3

в) 4 + 5/9 - 8/9 = 4 + (5/9 - 8/9) = 4 + (-3/9) = 4 - 1/3 = 12/3 - 1/3 = 11/3

г) 3 + 1/12 - 1 + 15/12 = 3 + (1/12 + 15/12) = 3 + (16/12) = 3 + 4/3 = 9/3 + 4/3 = 13/3

д) 6 + 3/7 - 5 + 5/7 = 6 - 5 + (3/7 + 5/7) = 1 + 8/7 = 1 + 1 1/7 = 2 1/7

е) 2 + 3/8 - 1 + 7/8 = 2 - 1 + (3/8 + 7/8) = 1 + 10/8 = 1 + 1 2/8 = 2 1/4
