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.)
