Answer:


Explanation:
Given
Scale Measurement


Required
Determine the possible actual measurement
First, calculate the equivalent ratio.



To do this, we pick a scale factor.
Assume the scale factor is 15.
The actual measurement will be:




When the scale ratio is calculated, we have:



Note that both have the same equivalent ratios of 12.
So, whatever the scale ratio you use, the equivalent ratio will be the same
