Those people with some math background find this relationship intuitive but I have run into many that do not.

I think your geometry teacher would be disappointed in your skills. Maybe you should have paid more attention in class.
Let me try this again: 200/160 = 1.25 AND 628/502 = 1.25
Try not to get confused and mix up the numerators and denominators (comparing 160/200 to 628/502 is not how to look at it).
