6 5/6 - (4 5/8 + 2 1/12) = 6 5/6 - (4 5/8 + 2 1/12)
= 6 5/6 - (4 5/8 + 2 1/12)
= 6 5/6 - (4 10/16 + 2 2/16)
= 6 5/6 - (4 12/16)
= 6 5/6 - 4 3/4
= 6 - 4 + 1 - 3/4
= 2 1/4

(2 3/4 + 3 5/6) - (7/16 + 5/24) = (2 3/4 + 3 5/6) - (7/16 + 5/24)
= 2 3/4 + 3 5/6 - (7/16 + 5/24)
= 2 3/4 + 3 5/6 - (7/16 + 5/24)
= 2 3/4 + 3 5/6 - (21/48 + 10/48)
= 2 3/4 + 3 5/6 - 31/48
= 2 3/4 + 3 5/6 - 31/48
= 5 3/4 - 31/48
= 5 - 31/48
= 4 17/48

(4 7/18 - (6 8/9 - 3 7/12) + 5 - 1 2/3 = (4 7/18 - (6 8/9 - 3 7/12) + 5 - 1 2/3
= 4 7/18 - (6 8/9 - 3 7/12) + 5 - 1 2/3
= 4 7/18 - (6 16/18 - 3 7/12) + 5 - 1 2/3
= 4 7/18 - (6 16/18 - 3 7/12) + 5 - 1 2/3
= 4 7/18 - 10 - 5 + 5 - 1 2/3
= -1 2/3

5 1/4 ÷ 2 1/4 ÷ 1 1/8 = (5 1/4) / (2 1/4) / (1 1/8)
= (21/4) / (9/4) / (9/8)
= (21/4) * (8/9)
= 168/36
= 4 2/3

5 1/3 1 3/4 1 2/7 = (5 1/3) (1 3/4) (1 2/7)
= (16/3) (7/4) (9/7)
= 16/3 7/4 9/7
= 48

(5 1/2 1/10 - 8 4/5) ÷ 1 1/15 - (2 1/4 1/5) = (5 1/2 1/10 - 8 4/5) ÷ 1 1/15 - (2 1/4 1/5)
= (11/2 1/10 - 44/5) ÷ 16/15 - (9/4 1/5)
= 11/20 - 44/5 / 16/15 - 9/20
= 11/20 - 44/5 15/16 - 9/20
= 11/20 - 165/16 - 9/20
= (1116 - 165)/20 - 9/20
= (176 - 165)/20 - 9/20
= 11/20 - 9/20
= 2/20
= 1/10
