Introduction:

In mathematics, the additive inverse of any number is a number that, when added to the original number, results in a sum of zero. In other words, it is the opposite of the original number.

Definition of Additive Inverse:

The additive inverse of a number is defined as the opposite of that number, or the number that, when added to the original number, results in a sum of zero.

Finding the Additive Inverse of -5/-9:

To find the additive inverse of -5/-9, we need to find the number that, when added to -5/-9, will result in a sum of zero.

-5/-9 is a negative fraction, so its additive inverse will be a positive fraction.

To find the additive inverse of -5/-9, we can use the following formula:

Additive inverse of a number = -1 x (the number)

So, the additive inverse of -5/-9 can be found by multiplying -5/-9 by -1:

-5/-9 x -1 = 5/9

Therefore, the additive inverse of -5/-9 is 5/9.

Conclusion:

The additive inverse of a number is the opposite of that number, or the number that, when added to the original number, results in a sum of zero. To find the additive inverse of a number, we can use the formula: Additive inverse of a number = -1 x (the number). In the case of -5/-9, its additive inverse is 5/9.

Additive inverse of -5/-9 is -5/9.
