The additive inverse of a number x, is the opposite of x which is -x. The given numbers and their opposite can be matched as:
- 1.3: -1.3.
- 4.5: -4.5.
- 3.1: -3.1.
- 5.4: - 5.4
Recall:
- The opposite of a number can be defined as its additive inverse.
- If x is a number, the additive inverse of the number x is the number that will be added to x that will equal zero.
- For example, if x is a number, the number that can added to x to give us 0 is -x, i.e. x + (-x) = 0.
- The additive inverse (opposite) of x is -x.
Therefore:
Opposite (additive inverse) of 1.3 is: -1.3.
Opposite (additive inverse) of 4.5 is: -4.5.
Opposite (additive inverse) of 3.1 is: -3.1.
Opposite (additive inverse) of 5.4 is: - 5.4
In summary, the additive inverse of a number x, is the opposite of x which is -x. The given numbers and their opposite can be matched as:
- 1.3: -1.3.
- 4.5: -4.5.
- 3.1: -3.1.
- 5.4: - 5.4
