Find the Multiplicative Inverse: Converting 12 to Its Reciprocal Form

To solve the problem of finding the inverse of 12, we follow these steps:

• Step 1: Identify the number given, which is 12.
• Step 2: Apply the reciprocal formula to find the inverse, which is $\frac{1}{\text{number}}$.

Now, let's work through the steps:
Step 1: We are given the number 12, and we need to find its inverse.
Step 2: Using the formula for the reciprocal, we have $\frac{1}{12}$.
The reciprocal of a positive number is positive, so the inverse is $\frac{1}{12}$.

Considering the answer choices provided, the correct choice is 3: $\frac{1}{12}$.

Therefore, the inverse of 12 is $\frac{1}{12}$.
