To solve the equation \( \frac{x}{4} = 12 \) using inverse operations, we can start by isolating \( x \).
Step 1: Multiply both sides of the equation by 4 to eliminate the fraction: \[ x = 12 \times 4 \]
Step 2: Calculate the right side: \[ x = 48 \]
Thus, the solution is: \[ x = 48 \]
The correct response is: Inverse operation is multiplication; x = 48.
