Szczegółowe wyjaśnienie:
Odpowiedź:
2 i 1/8 - 1 i 2/8 = 1 i 9/8 - 1 i 2/8 = 7/8
5/14 - 3/14 = 2/14 = 1/7
5 i 3/7 - 2 i 5/7 = 4 i 10/7 - 2 i 5/7 = 2 i 5/7
12 i 4/18 - 8 i 9/15 = 12 i 60/270 - 8 i 162/270 = 11 i 330/270 - 8 i 162/270 = 3 i 168/270 = 3 i 84/135 = 3 i 28/45
138 i 27/108 - 38 i 53/108 = 137 i 135/108 - 38 i 53/108 = 99 i 82/108 = 99 i 41/54
