Additive inverse means the opposite side of the number line. So, the additive inverse of 15 is -15 and the additive inverse of -4/5 is 4/5. I think you can do the rest. Multiplicative inverse meansflip the fraction." So, the multiplicative inverse of 15 = 15/1 is 1/15. The multiplicative inverse of -4/5 is -5/4. 1.25 is a little more tricky. You need to first turn it into a mixed number. This would be 1 1/4. Next you need to turn the mixed number into an improper fraction. This would be 5/4. Now you canflip the fraction." The multiplicative inverse would be 4/5. I think you can do the rest.
