Answer 2

1. 4 5/9 + 2 4/9 = 6 9/9 = 7

2. 10 - 3 2/5 = 10 - (3 + 2/5) = 10 - (15/5 + 2/5) = 10 - 17/5 = 48/5

3. 11 1/4 - 33/4 = 44/4 + 1/4 - 33/4 = (44 + 1 - 33)/4 = 12/4 = 3

4. 10 5/6 - 1 2/6 = (10 - 1) + (5/6 - 2/6) = 9 + 3/6 = 9 + 1/2 = 9 1/2

5. 10 5/6 - 1 2/6 = 9 1/2 (Same as the previous question)

6. 12 - 5 2/7 = 12 - (5 + 2/7) = 12 - (35/7 + 2/7) = 12 - 37/7 = (84 - 37)/7 = 47/7 = 6 5/7

7. 1 5/7 + 2 1/7 = (1 + 2) + (5/7 + 1/7) = 3 + 6/7 = 3 6/7

8. 4 5/6 + 32/6 = (4 + 32/6) = (4 + 5 2/6) = (4 + 5 + 1/3) = 9 1/3

9. 17 - 7 7/3 = (17 - 7) - (7/3) = 10 - 7/3 = (10 * 3 - 7)/3 = 23/3 = 7 2/3

I hope these answers are helpful!
