(2 5/8 + 2 1/2) - 4 2/3

Steps:
1. Do 2 5/8 + 2 1/2 by changing them so they have the same denominators. Since 2 goes into 8, 8 would be your common denominator.
2. Multiply 2 times 4 which equals 8. Multiply 1 times 4 which equals 4
3. Your new problem is 2 5/8 + 2 4/8
4. This equals 4 9/8 which equals 5 1/8
5. Do 5 1/8- 4 2/3 by multiplying both denominators and numerators by 3 and the second mixed number by 8
6. 8 times 3 equals 24
1 times 3 equals 3
7. 5 3/24
8. 3 times 8 equals 24
9. 2 times 8 equals 16
10. 5 3/24 - 4 16/24
11. Take from the whole number in 5 3/24
12. 4 27/ 24 - 4 16/24
13. Your answer is 11/24

The answer would be the second choice : )
