Answer:
The scale factor expressed as a fraction is 4/5
Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.
This is expressed as:
Taking the ratio of the fractions
\frac{20}{25} = \frac{4}{5}
25
20
=
5
4
Similarly for \frac{12}{15}
15
12
\frac{12}{15} =\frac{4}{5}
15
12
=
5
4
This shows that \frac{20}{25} = \frac{12}{15} = \frac{4}{5}
25
20
=
15
12
=
5
4
Hence the scale factor expressed as a fraction is 4/5
