А) 1- 5/8= 8/8-5/8=(8-5)/8= 3/8
б) 1- 1/6= 6/6 - 1/6 = (6-1)/6= 5/6
в) 6 - 2/5 = 30/5 - 2/5 = (30-2)/5= 28/5= 5 целых 3/5
г) 5-2/3= 15/3 - 2/3= (15-2)/3 = 13/3= 4 целых 1/3
д) 8 - 4 целых 7/8= 64/8 - 39/8 = (64-39)/8 = 25/8 = 3 целых 1/8
е) 10 - 1 целая 1/9= 90/9 - 10/9 =(90-10)/9 = 80/9= 8 целых 8/9
