A sum of 7 4/6 plus 4 3/6 as a mixed number

12 16/100 is the mixed number

Because the denominators are the same you can just add:

add the whole numbers:

7+4=11

add the numerators:

4+3=7

after doing that you now have:

11 7/6

now make 11 7/6 into a proper mixed number:

11 7/6 - - > 12 1/6

the answer is 12 1/6
