Explicație pas cu pas:
1/2 + 1/8 = 4/8 + 1/8 = 5/8
1/6 + 2/3 = 1/6 + 4/6 = 5/6
3/11 + 1/22 = 6/22 + 1/22 = 7/22
3/8 + 5/16 = 6/16 + 5/16 = 11/16
7/4 + 1/2 = 7/4 + 2/4 = 9/4
3/7 + 9/14 = 6/14 + 9/14 = 15/14
1/3 + 2/5 = 5/15 + 6/15 = 11/15
5/6 + 1/5 = 25/30 + 6/30 = 31/30
2/5 + 7/3 = 6/15 + 35/15 = 41/15
1/2 + 1/3 + 5/6 = 3/6 + 2/6 + 5/6 = 10/6 = 5/3
1/3 + 5/6 + 3/4 + 7/24 = 8/24 + 20/24 + 18/24 + 7/24 = 53/24
