Explicație pas cu pas:

3/5 + 1/10 + 7/6 + 4/5 = 7/5 + 1/10 + 7/6 = 42/30 + 3/30 + 35/30 = 80/30 = 8/3

2/3 + 1/6 + 5/8 + 11/12 = 16/24 + 4/24 + 15/24 + 22/24 = 57/24 = 19/8

4/18 + 3/4 + 1/9 + 5/6 = 8/36 + 27/36 + 4/36 + 30/36 =  69/36 = 23/12

5/21 + 6/7 + 5/42 + 9/14 = 10/42 + 36/42 + 5/42 + 27/42 = 78/42 = 39/21 = 13/7

1/10 + 7/12 + 1/15 + 4/30 = 6/60 + 35/60  + 4/60 + 8/60 = 53/60

5/36 + 1/18 + 3/24 + 1/4 = 10/72 + 4/72 + 9/72 + 18/72 = 41/72
