A number multiplied by its multiplicative inverse equals what value?

When a number is multiplied by its multiplicative inverse, the result is always 1. The multiplicative inverse of a number (x) is defined as (\frac{1}{x}), provided that (x) is not equal to zero. Therefore, if you take any non-zero number (x) and multiply it by its multiplicative inverse (\frac{1}{x}), the calculation goes as follows:

[

x \times \frac{1}{x} = 1

]

This property holds true for all non-zero numbers in mathematics.

For the case when the number is zero, the multiplicative inverse is undefined, as you cannot divide by zero. This is why the multiplicative inverse is typically only discussed in context to non-zero numbers.

Thus, the correct conclusion is that a number multiplied by its multiplicative inverse results in the value 1, validating the choice that reflects this fundamental property of numbers.
