Answer 1

8 3/4 - 3 1/6 = 35/4 - 19/6 = 105/12 - 38/12 = 67/12 = 5 7/12

8 2/3 - 3 4/5 = 26/3 - 19/5 = 130/15 - 57/15 = 73/15 = 4 13/15

3/7 + 5/9 = 27/63 + 35/63 = 62/63

9 2/4 - 5 1/2 = 38/4 - 11/2 = 38/4 - 22/4 = 16/4 = 4

9 3/4 - 3 7/8 = 39/4 - 31/8 = 78/8 - 31/8 = 47/8 = 5 7/8

11 1/2 + 1 3/6 = 23/2 + 9/6 = 23/2 + 3/2 = 25/2 = 12 1/2

9 2/3 + 2 3/4 = 29/3 + 11/4 = 116/12 + 33/12 = 149/12 = 12 5/12

2/9 + 1/12 = 8/36 + 3/36 = 11/36

1 4/7 + 4 5/8 = 11/7 + 37/8 = 88/56 + 259/56 = 347/56 = 6 11/56

5 5/6 + 6 7/8 = 35/6 + 55/8 = 140/24 + 165/24 = 305/24 = 12 17/24

1/4 - 7/36 = 9/36 - 7/36 = 2/36 = 1/18

7 5/6 - 2 3/8 = 47/6 - 19/8 = 188/24 - 57/24 = 131/24 = 5 11/24

4/25 + 2/15 = 12/75 + 10/75 = 22/75

7/6 + 2/9 = 42/36 + 8/36 = 50/36 = 1 14/36 = 1 7/18

3 7/18 - 2 1/4 = 61/18 - 9/4 = 122/36 - 81/36 = 41/36 = 1 5/36

17 2/3 - 4 7/8 = 53/3 - 39/8 = 424/24 - 117/24 = 307/24 = 12 19/24

40 - 9 3/4 = 30 1/4

2 8/9 + 5 5/6 = 26/9 + 35/6 = 104/36 + 210/36 = 314/36 = 8 26/36 = 8 13/18
