You have to make the fractions an improper fraction. For 4 3/4 first multiply 4x4 which is 16 then 16+3 which is 19/4. For 2 2/3 multiply 3x2 which is 6 then 6+2 which is 8/3. Now make 19/4 and 8/3 denominators same. 19/4 becomes 57/12 by multiplying 19x3 which is 57 and 4x3 which is 12. 8/3 becomes 32/12 by multiplying 8x4 which is 32 and 3x4 which is 12. Then add 57/12+32/12 which is 89/12. Now make 89/12 into a mixed number. The mixed number is 7 5/12.
Hope that helped:)
