Proportional Reasoning Review : Similar Polygons

In the text book, I had a bit of a struggle on 3rd question, specifically b. I don’t really know what was going through my brain, but I guess I only looked at 2 sides and made an assumption. The 2 sides I looked at were SR/WV and TU/XY. Both of those are correct (with 5/1) The other 2 sides, however, add up to 4.06, which is obviously not the same thing.

That video explains fairly well the concepts in which we learned in class, and is easy to follow.
