Answer 1

1) = 8/10 + 3/7 = 4/5 + 3/7 = 28/35 + 15/35 = 43/35 = 1 8/35

2) = 3 1/3 - 2 5/10 = 3 1/3 - 2 1/2 = 3 2/6 - 2 3/6 = 2 8/6 - 2 3/6 = 5/6

4) = 26 1/11 - 5 7/10 = 26 10/110 - 5 77/110 = 25 120/110 - 5 77/110 = 20 43/110

5) = 40 8/10 + 15 2/3 = 40 4/5 + 15 2/3 = 40 12/15 + 15 10/15 = 55 22/15 = 56 7/15
