To find the sum of these two numbers, we need to subtract the second number from the first number.

The additive inverse of a number x is the number that, when added to x, equals zero. So, the additive inverse of −8 5/6 is 8 5/6.

Now, we can rewrite the given expression as −12 2/3 + 8 5/6.

To add these fractions, we need a common denominator.

The least common multiple of 3 and 6 is 6.

Converting both fractions to have a denominator of 6, we get:

−12 2/3 + 8 5/6 = −12 * 2/3 * 2/2 + 8/1 * 5/6 * 1/1
= −24/6 + 40/6

Now, we can add the two fractions:

−24/6 + 40/6 = 16/6

Simplifying the fraction, we get:

16/6 = 8/3

So, the answer is 8/3, which can be written as a mixed number as 2 2/3.
