-8 5/24

Step-by-step explanation:

First you'll want a common denominator, so we go with 24, since both 6 & 8 can be multiplied to 24. For -5/6, times both by 4 to get -20/24. For -3/8, times both by 3 to get -9/24. Add those up, you get -29/24. So it isn't an improper fraction, simplify to -1 5/24. Add the whole numbers to that and you should get -8 5/24, and since we can't simplify, that's your final answer.
