Answer 1

1 3/4+2 1/2 = 7/4 + 5/2 = 7/4 + 10/4 = 17/4 = 4 1/4

 

 

 

3 2/9+1 2/3 = 29/9 + 5/3 = 29/9 + 15/9 = 44/9 = 4 8/9

 

 

 

4 4/5+1 1/2 = 24/5 + 3/2 = 48/10 + 15/10 = 63/10 = 6 3/10

 

 

 

4/5+3/4+2/5 = 16/20 + 15/20 + 8/20 = 39/20 = 1 19/20

 

 

 

5/7+1/2+6/7 = 10/14 + 7/14 + 12/14 = 29/14 = 2 1/14

 

 

 

2/8+1/3+5/8 = 6/24 + 8/24 + 15/24 = 29/24 = 1 5/24

 

 

 

1 5/6+2 2/3+1 4/9 = 11/6 + 8/3 + 13/9 = 33/18 + 48/18 + 26/18 = 107/18 = 5 17/18

 

 

 

1 3/8+2 1/3+1 5/6 = 11/8 + 7/3 + 11/6 = 33/24 + 56/24 + 44/24 = 133/24 = 5 13/24

 

 

 

2 7/10+1 3/4+4/5 = 27/10 + 7/4 + 4/5 = 54/20 + 35/20 + 16/20 = 105/20 = 5 5/20 = 5 1/4
