Which of the following represents the additive inverse of 125? A. - (-125) B. 125 C. - 125 D. 1/25

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
