1/8 + 1/4 = 1/8 + 2/8 = 3/8
3/4 - 1/3 = 9/12 - 4/12 = 5/12
1/2 + 5/12 = 6/12 + 5/12 = 11/12
7/10 - 3/5 = 7/10 - 6/10 = 1/10
2/3 + 1/4 = 8/12 + 3/12 = 11/12
1/5 + 1/3 = 3/15 + 5/15 = 8/15
3/4 + 1/8 = 6/8 + 1/8 = 7/8
5/7 - 1/3 = 15/21 - 7/21 = 8/21
1/6 + 1/4 = 2/12 + 3/12 = 5/12
1/4 + 2/3 = 3/12 + 8/12 = 11/12
