To find the additive inverse of a number, we simply change the sign of the number.

The additive inverse of -24 4/5 is 24 4/5.
The additive inverse of -6 7/10 is 6 7/10.

Now, we can add the two numbers together:

24 4/5 + 6 7/10 = 30 9/10

However, since we changed the sign of both numbers, the final answer will also be negative.

Therefore, the correct answer is:

A. -31 1/10
