the complete question is
Parallelogram APFM is similar to parallelogram AEVT .
What is the scale factor of a dilation from APFM to AEVT ?
the picture in the attached figure
we know that
scale factor=TV/MF-----> 49.2/82-----> scale factor=0.6
0.6=6/10-----> 3/5
therefore
the answer is
the scale factor of a dilation from APFM to AEVT is 3/5
