Answer:
Mark 2/3, -2/3, and sum to 0
Explanation:
Additive inverses basically mean the opposite of the number. Since the number is 2/3, the additive inverse to it would be -2/3. You would mark p to -2/3, and 2/3 to 2/3. Then, if you do 2/3+(-2/3) it would be 0. You would drag sum to 0.
Hope that helped!!
