Answer 1

2 2/3-1 4/5= 2 10/15 - 1 12/15 = 1 25/15 - 1 12/15 = 1 13/15
1 2/6 -2/3= 1 2/6 - 4/6 = 8/6 - 4/6 = 4/6 = 2/3
2 1/4-1 6/8= 2 2/8 - 1 6/8 = 1 10/8 - 1 6/8 = 4/8 = 1/2
3 1/3 -2 10/15 = 3 10/30 - 2 20/30 = 2 40/30 - 2 20/30 = 20/30 = 2/3
9 1/2- 3 5/8= 9 4/8 - 3 5/8 = 8 12/8 - 3 5/8 = 5 7/8
5 1/10-4 3/5= 5 1/10 - 4 6/10 = 4 11/10 - 4 6/10 = 5/10 = 1/2
2 1/21- 1 5/7= 2 1/21 - 1 15/21 = 1 22/21 - 1 15/21 = 7/21 = 1/3
1 1/5- 39/50 = 1 10/50 - 39/50 = 60/50 - 39/50 = 21/50

Answer 2

2 2/3-1 4/5= 2 i 10/15 - 1 i 12/15 = 1 i 25/15 - 1 i 12/15 = 13/15
1 2/6 -2/3= 1 i 2/6 - 4/6 = 8/6 - 4/6 = 4/6 = 2/3
2 1/4-1 6/8= 2 i 2/8 - 1 i 6/8 = 1 i 10/8 - 1 i 6/8 = 4/8 = 1/2
3 1/3 -2 10/15 = 3 i 5/15 - 2 i 10/15 = 2 i 20/15 - 2 i 10/15 = 10/15 = 2/3
9 1/2- 3 5/8= 9 i 4/8 - 3 i 5/8 = 8 i 12/8 - 3 i 5/8 = 5 i 7/8
5 1/10-4 3/5= 5 i 1/10 - 4 i 6/10 = 4 i 11/10 - 4 i 6/10 = 5/10 = 1/2
2 1/21- 1 5/7= 2 i 1/21 - 1 i 15/21 = 1 i 22/21 - 1 i 15/21 = 7/21 = 1/3
1 1/5- 39/50 = 1 i 10/50 - 39/50 = 60/50 - 39/50 = 21/50
