OG DS #80

[cpkelley5]

The questions is:

[deleted because problem is from a banned source - see below]

I chose answer B, however OG says the answer is D. My rationale...

2) is correct

1) Once you cross multiply you get r = 3s/4. If r is any number above 1, than r>s and the statement is sufficient. However, if r is a fraction then s>r.

For instance, if 1/2 = 3s/4, then s=2/3, correct? So, why does OG not take into consideration fractions here? It says r & s are great than 0....not 1.

What am I missing?
