1) 5 (8/51) - 3 (5/17) = 5 (8/51) - 3 (15/51) = 4 (59/51) - 3 (15/51) = 1 (44/51)

2) 4 (2/9) - 1 (17/36) = 4 (8/36) - 1 (17/36) = 3 (44/36) - 1 (17/36) = 2 (3/4)

3) 6 (2/3) - 2 (6/7) = 6 (14/21) - 2 (18/21) = 3 (17/21)

4) 3 (1/6) - 2 (3/8) = 3 (4/24) - 2 (9/24) = 19/24

5) 9 (7/20) - 4 (9/25) = 9 (35/100) - 4 (36/100) = 4 (99/100)

6) 7 (4/15) - 5 (5/9) = 7 (12/45) - 5 (25/45) = 1 (32/45)
