3 1/6 = 3 3/18 8 2/9 = 8 4/18 1 1/2 = 1 9/18. Now add all the numerators of the fractions together that equals 16so your fraction is 16/18 Now add all your whole numbers together that equals 12. So now you have 12 16/18 now reduce to lowest terms equals 12 8/9
Simple...
you have:
To convert to a mixed number divide 68 by 7-->>
Leaving you with ->
Thus, your answer.
