6).
1 3/7 + 2 2/5 + 4/10
= 10/7 + 12/5 + 4/10
= 100/70 + 168/70 + 28/70
= 296/70 = 148/35

7).
3 1/3 + 4/6 + 6 3/5
= 10/3 + 4/6 + 33/5
= 100/30 + 20/30 + 198/30
= 318/30 = 53/5

8).
2 2/4 + 5 1/3 + 3/8
= 10/4 + 16/3 + 3/8
= 60/24 + 128/24 + 9/24
= 197/24

9).
4 3/4 + 2 1/3 + 1 1/2
= 19/4 + 7/3 + 3/2
= 57/12 + 28/12 + 18/12
= 103/12
