1/2 + 3/4 = 0,5 + 0,75 = 1,25 = 1 i 1/4
2/3 + 1/6 = 5/6
6/7 + 15/14 = 27/14 = 1 i 13/14
1/2 + 1/5 + 1/10 = 5/10 + 2/10 + 1/10 = 8/10 = 4/5 = 0,8
1/3 + 3/5 = 5/15 + 9/15 = 14/15
5/6 + 1/4 = 10/12 + 3/12 = 13/12 = 1 i 1/12
1/6 + 1/10 + 1/15 = 5/30 + 3/10 + 2/30 = 10/30 = 1/3
4/5 + 5/6 = 24/30 + 25/30 = 49/30 = 1 i 19/30

1/2 + 3/4 = 2/4 + 3/4 = 5/4 = 1 ¼

2/3 + 1/6 =4/6 + 1/6 = 5/6

6/7 + 15/14 = 12/14 + 15/14 = 27/14 = 1 13/14

1/2 + 1/5 + 1/10 = 5/10 + 2/5 + 1/10 = 8/10 = 4/5

1/3+3/5 = 5/15 + 9/15 = 14/15

5/6 + 1/4 = 10/12 + 3/12 = 13/12 = 1 1/12

1/6 + 1/10 + 1/15 = 10/60 + 6/10 + 4/60 = 20/60 = 2/6 = 1/3

4/5 + 5/6 = 24/30 + 25/30 = 49/30 = 1 19/30
