5 5/12+5/6 = 6 1/4
5/6 приводим к знаменателю 12 = 10/12
5 5/12+10/12 = 5 15/12 = 5 5/4 = 6 1/4
1 3/8+7 5/6 = 9 5/24
8/8+3/8 = 11/8
7 5/6 = 42/6+5/6 = 47/6
общий знаменатель - 24
11/8=33/24
47/6 = 188/24
33/24+188/24=221/24 = 9 5/24
5 4/5 - 3 1/5 = 2 3/5
4 3/11 - 5/22 = 4 6/22-5/22 = 4 1/22
8 7/8 - 4 5/6 = 8 21/24 - 4 20/24 = 4 1/24
3) 2 1/5+7/15 = 2 3/15+7/15 = 2 10/15 = 2 2/3
4 8/15+4/9 = 4 24/45+20/45 = 4 44/45
2 6/7-1/7 = 2 5/7
3 5/6 - 1 3/4 = 3 20/24 - 1 18/24 = 2 2/24 = 2 1/12
5 5/12 - 3 3/8 = 5 10/24 - 3 9/24 = 2 1/24
