Answer 2

12 9/13 - 8 = 4  9/13

 

7 - 3 5/11 = 3  6/11

 

3 2/3 + 5/7 = 3  14/21 + 15/21 = 3  29/21 = 4  8/21

 

2 3/8 + 4 4/5 = 2  15/40 + 4  32/40 = 6 47/40 = 7  7/40

 

7 3/4 - 5 2/3 = 7  9/12 - 5  8/12 = 2  1/12

 

8 1/5 - 4 5/6 = 8  6/30 - 4  25/30 = 3  11/30

 

1 6/9 + 3 11/18 =1  12/18 + 3  11/18 = 4  23/18 = 5  5/18

 

5 2/7 - 1 9/21 =5  6/21 - 1  9/21 = 3  18/21 = 3  6/7
