You could turn them both into improper fraction. 15 1/6 would now be 91/6. Then 6 5/12 would be 77/12. 6 and 12 common denominator is 12 so 91/6=182/12. 77/12 = 77/12. 182/12- 77/12= 105/12. Then you turn 105/12 into a mixed number which would be 8 9/12= 8 3/4.

Do what is in parenthesis first. You get 12 + {12 - 36/4} Next do what is in the brackets 12 - 36/4 = 48/4 - 36/4 = 12/4 = 3 or 12 - 9 = 3 whichever way you prefer. Then, you are left with 12 - 3 Hope this makes sense!
