1. - We need to add fractions
4 6/8 + 3 2/3 = 8 1/2
2. Adding fractions.
8 1/2 + 4 2/4 = 13
3. Once again, adding fractions.
2 4/6 + 5 1/2 = 8 1/6
Those are the answers to 1, 2 and 3!
Please know that these were from my mind, so they may be wrong.
Although, I did my best, and I think they are all right.
Glad I could help, and good luck!
