Answer 1

3 2/7 + 5 3/14 = 3 4/14 + 5 3/14 = 8 7/14 = 8 1/2,

5 7/8 + 2 5/12 = 5 21/24 + 2 10/24 = 7 31/24 = 8 7/24,

7 3/8 + 1 5/6 = 7 9/24 + 1 20/24 = 8 29/24 = 9 5/24,

1 1/9 + 2 3/5 = 1 5/45 + 2 27/45 = 3 32/45,

7 2/9 + 4 = 11 2/9,

8 3/5 + 1/15 = 8 9/15 + 1/15 = 8 10/15 = 8 2/3,

7 + 3 5/8 = 10 5/8,

2/3 + 4 3/5 = 10/15 + 4 9/15 = 4 19/15 = 5 4/15
