What is the additive inverse of −3 3/4?

Explanation:
Additive inverse is the opposite number that makes the sum zero. For -3 3/4, its opposite is 3 3/4. If you check by converting to fractions, -3 3/4 equals -15/4, and the opposite is +15/4, which is 3 3/4. Adding them gives -15/4 + 15/4 = 0, confirming the result. So the additive inverse is 3 3/4. The other options wouldn’t sum to zero when added to -3 3/4.
