Calculate the Multiplicative Inverse: Finding 1/3

To solve this problem, we need to find the inverse of the number 3. In mathematics, the term "inverse" in this context refers to the multiplicative inverse. The multiplicative inverse or reciprocal of a number is defined as a number which, when multiplied by the original number, gives a product of 1.

Given the number 3, its reciprocal is calculated by dividing 1 by the number:

$\text{Reciprocal of 3} = \frac{1}{3}$

This means that the multiplicative inverse of 3 is $\frac{1}{3}$.

Therefore, the solution to the problem is $\frac{1}{3}$.
