scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

x-3y=4
