1) 8 1\4 - 5 1\2 = 33/4 - 11/2 = 33/4 - 22/ = 11\4 = 2 3\4

2) 7 4/15 - 4 3/5 = 105/15 - 23\5 = 105/15- 69/15 = 36/15 = 12/5 = 2 2\5

3) 12 2\5 - 5 3/4 = 62/5 - 23/4 = 248/20 - 115/20= 133/20 = 6 13/20

4) 6 3/10 - 4 7/15 = 63/10 - 67/15 = 189/30 - 134/30 = 55/30 = 11\6 = 1 5/6

5) 9 5\18 - 1 7\12 = 162/18 - 19/12 = 324/36 - 57/36 = 267/36 = 7 15/36 = 7 5/12

6) 8 7/15 - 2 17/18 = 120/15 - 36/18 = 960/120 - 288/120 = 672/120 = 5 72\120 = 5 3/5

7) 8 2/3 - 7 5/7 = 26/3 - 54/7 = 182/21 - 162/ 21 = 20/21

8) 7 3/16 - 1 5/24 = 112/16 - 29/24 = 336/48 - 58/48 = 278/48 = 5 38/48 = 19/24
