Additive inverse of 125 is – 125, option C is correct.
<u>Solution:</u>
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, <em>sum of a number and its additive inverse equals to 0.
</em>
So, let us check option by option.
<em><u>Option A:</u></em>
Given number is -(-125)
-(-125) ⇒ 125 + ( - ( - 125 ) )
⇒ 125 + 125
⇒ 250 ⇒ wrong option
<em><u>Option B:</u></em>
Given number is 125
⇒ 125 + 125 ⇒ 250 ⇒ wrong option
<em><u>Option C:</u></em>
Given number is -125
125 + ( - 125 ) ⇒ 125 – 125 ⇒ 0 ⇒ correct option
Hence, additive inverse of 125 is – 125, option C is correct
