Jawaban:

1. 3 2/3 + 4 4/5 = (3+4) + (2/3 + 4/5) = 7 + (10/15 + 12/15) = 7 22/15 = 7 + (1 + 7/15) = 8 7/15

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

3. 5 5/6 + 2 1/4 = (5+2) + (5/6 + 1/4) = 7 + (10/12 + 3/12) = 7 13/12 = 7 + (1 + 1/12) = 8 1/12

4. 6 1/3 + 4 4/5 = (6+4) + (1/3 + 4/5) = 10 + (5/15 + 12/15) = 10 17/15 = 10 + (1 + 2/15) = 11 2/15

5. 4 2/3 + 2 3/4 = (4+2) + (2/3 + 3/4) = 6 + (8/12 + 9/12) = 6 17/12 = 6 + (1 + 5/12) = 7 5/12
