Answer:
The exact form is 161/12 but the mixed number is 13 5/12
Explanation:
You need to find a common donominator for all of the fractions 2,3,4 all go into 12 so I multiplied 1/2x6 (multiply both 1 and 2 by 6 same with all the others) then 2/3x4 and 1/4x3. That should get you 6/12 8/12 and 3/12. Add all of those and then add all of the whole numbers.
