Answer 1

5/9 + 2/9 = 7/9
4/7 + 5/7 = 9/7 = 1 i 2/7
2 i 2/7 + 3/7 = 2 i 5/7
2 i 3/5 + 3 i 4/5 = 5 i 7/5 = 6 i 2/5
12/13 - 8/13 = 4/13
4 i 13/11 - 2 i 6/11 = 2 i 7/11
7 - 5/8 = 6 i 8/8 - 5/8 = 1 i 3/8
3 i 1/8 - 1 i 5/8 = 2 i 9/8 - 1 i 5/8 = 1 i 4/8 = 1 i 1/2

Answer 2

5/9+2/9=7/9
4/7+5/7=9/7          9/7=1 2/7
2 i 2/7+3/7=2 i 5/7
2 i 3/5+3 i 4/5=5 i 7/5       5 i 7/5=6 i  2/5
12/13-8/13=4/13
4 i 13/21-2 i 6/11= 2 i 17/231
7-5/8=     7=6 i 8/8      6 i 8/8-5/8=6 i 3/8
3 i 1/8-1 i 5/8=     3 i 1/8=2 i 9/8        2 i 9/8-1 i 5/8=1 i 4/8
