Кчислу в рамке 1/2 прибавь каждое числи в столбце: +1/5 +4/5 1/8 1 1/3 1/9 1/3 1/2 2/3 2 1/6 1/7 1/4 2/5 1 1/12 1/10 3/7 к ним всем нужно прибавить 1/2

1/5 + 1/2 = 2/10 + 5/10 = 7/10
4/5 + 1/2 = 8/10 + 5/10 = 13/10 = 1_3/10
1/8 + 1/2 = 1/8 + 4/8 = 5/8
1_1/3 + 1/2 = 1_2/6 + 3/6 = 1_5/6
1/9 + 1/2 = 2/18 + 9/18 = 11/18
1/3 + 1/2 = 2/6 + 3/6 = 5/6
1/2 + 1/2 = 2/2 = 1
2/3 + 1 /2 = 4/6 + 3/6 = 7/6 = 1_1/6
2_1/6 + 1/2 =2_1/6 + 3/6 = 2_4/6 = 2_2/3
1/7 + 1/2 = 2/14 + 7/14 = 9/14
1/4 + 1/2 = 1/4 + 2/4 = 3/4
2/5 +1/2 = 4/10 + 5/10 = 9/10
1_1/12 + 1/2 = 1_1/12 + 6/12 = 1_7/12
1/10 + 1/2 = 1/10 + 5/10 = 6/10 = 3/5
3/7 + 1/2 = 6/14 + 7/14 = 13/14
