1) 6 (4/15) - 2 (1/9) + 1 (3/10) = 6 (24/90) - 2 (10/90) + 1 (27/90) = 5 (41/90).

2) 7 (2/3) - 5 (5/36) + 3 (3/8) = 7 (48/72) - 5 (10/72) + 3 (27/72) = 5 (65/72).

3) 10 (9/22) - 3 (7/11) - 4 (8/33) = 10 (27/66) - 3 (42/66) - 4 (16/66) = 2 (35/66).

4) 12 (17/42) - (3 (1/4) + 4 (1/6)) = 12 (17/42) - (3 (3/12) + 4 (2/12)) = 12 (17/42) - 7 (5/12) = 4 (83/84).

5) 15 - (6 (4/35) - 2 (3/14)) = 15 - (6 (8/70) - 2 (15/70)) = 15 - 3 (63/70) = 11 (1/10).
