1052.
1) 8 1/5 + 5 1/6 - 3 1/5 = 8 6/30 + 5 5/30 - 3 6/30 = 10 5/30 = 10 1/6
2) 8 1/8 + 1 2/3 - 3 1/4 = 8 3/24 + 1 16/24 - 3 6/24 = 6 13/24
3) 6 1/4 - 2 5/7 + 6 3/14 = 6 7/28 - 2 20/28 + 6 6/28 = 5 35/28 - 2 20/28 + 6 6/28 = 9 21/28 = 9 3/4
4) 5 2/3 + 2 1/4 - 1 1/5 = 5 40/60 + 2 15/60 - 1 12/60 = 6 43/60

1053.
1) 7 - 3/5 + 2 7/9 = 6 5/5 - 3/5 + 2 7/9 = 6 45/45 - 27/45 + 2 35/45 = 8 53/45 = 9 8/45
2) 5 2/7 - 1/3 + 6 = 5 6/21 - 7/21 + 126/21 = 4 27/21 - 7/21 + 126/21 = 4 146/21 = 10 20/21
3) 9 + 1 3/4 - 2/5 = 8 4/4 + 1 3/4 - 2/5 = 8 20/20 + 1 15/20 - 8/20 = 9 27/20 = 10 7/20
4) 3 5/12 - 4/5 + 31/60 = 3 25/60 - 48/60 + 31/60 = 2 85/60 - 48/60 + 31/60 = 2 68/60 = 3 8/60 = 3 2/15
