Additive inverse of 125 is – 125, option C is correct.
Solution:
Given that , a number is 125
We have to find the additive inverse for the above given number from the above given set of options.
Now, we know that, sum of a number and its additive inverse equals to 0.
So, let us check option by option.
Option A:
Given number is -(-125)
-(-125) ⇒ 125 + ( - ( - 125 ) )
⇒ 125 + 125
⇒ 250 ⇒ wrong option
Option B:
Given number is 125
⇒ 125 + 125 ⇒ 250 ⇒ wrong option
Option C:
Given number is -125
125 + ( - 125 ) ⇒ 125 – 125 ⇒ 0 ⇒ correct option
Hence, additive inverse of 125 is – 125, option C is correct
