Answer 1

To find the sum of -24 4/5 and -6 7/10 using the additive inverse, you can first find the additive inverse of -6 7/10 which would be 6 7/10.

Now, the problem becomes: -24 4/5 + 6 7/10

Converting both fractions to have a common denominator of 10, we get: -24 8/10 + 6 7/10

Now you can add the whole numbers and the fractions separately:

-24 + 6 = -18
8/10 + 7/10 = 15/10 = 1 5/10 = 1 1/2

Therefore, -24 4/5 - 6 7/10 = -18 1/2.
