Additive inverse of 5 1/2
To find the additive inverse of a number, you need to find the number that, when added to the given number, results in zero.
The additive inverse of a whole number is the negative of that number. For example, the additive inverse of 5 is -5.
To find the additive inverse of a mixed number, you need to convert it into an improper fraction first.
In your case, the mixed number is 5 1/2. To convert it into an improper fraction, you multiply the whole number (5) by the denominator of the fraction (2), and then add the numerator (1). This gives us (5 * 2) + 1 = 11. So, 5 1/2 can be written as the improper fraction 11/2.
Now, to find the additive inverse of 5 1/2, simply change the sign of the numerator. This gives us -11/2.
Therefore, the additive inverse of 5 1/2 is -11/2.
