METHOD: RATIO table

This should be fairly easy if you use the method we have practiced. Assuming you have the method down, the only reason to get this wrong is a careless arithmetic error.

For those of you making these errors, I hope you're starting to see why it's a better use of your limited test taking time to double check your work on the medium questions than to rip your hair out and spend a lot of time trying to puzzle out the hardest questions which very few people can answer. (Listen try those last ones if you get there, *but first* make sure you think through these medium ones on which most people can more consistently score points.)
