enter your answer in the box.
k =

Explanation:

Step1: Recall the formula for scale factor

The scale factor \(k=\frac{\text{new length}}{\text{original length}}\)

Step2: Substitute the given values

The new height (after reduction) is \(4.8\) inches and the original height is \(12\) inches. So \(k = \frac{4.8}{12}\)

Step3: Calculate the value

\(k=\frac{4.8}{12}=0.4\)

Answer:

\(0.4\)
