Answer 1

1 - 1/7 = 7/7 - 1/7 = 6/7

2 - 1/7 = 1 i 7/7 - 1/7 = 1 i 6/7

6 - 1/7 = 5 i 7/7 - 1/7 = 5 i 6/7

 

 

1 - 2/5 = 5/5 - 2/5 = 3/5

2 - 2/5 = 1 i 5/5 - 2/5 = 1 i 3/5

5 - 2/5 = 4 i 5/5 - 2/5 = 4 i 3/5

 

2 - 7/12 = 1 i 12/12 - 7/12 = 1 i 5/12

3 - 7/12 = 2 i 12/12 - 7/12 = 2 i 5/12

5 - 7/12 = 4 i 12/12 - 7/12 = 4 i 5/12

 

3 - 2 i 5/9 = 2 i 9/9 - 2 i 5/9 = 4/9

5 - 2 i 5/9 = 4 i 9/9 - 2 i 5/9 = 2 i 4/9

12 - 2 i 5/9 = 11 i 9/9 - 2 i 5/9 = 9 i 4/9
