Is p/m>0?

1) p>m

2) pm>0.

Remember, if the product of any number of variables is > or < 0 then so will be the case for the product of the reciprocals of those variables.

In fact, to generalize any combination (either as direct products or products of the reciprocals) of a set of variables will yield the same parity wrt 0.

For example abcd/ef >0=> abcdef>0, ab/cdef>0, a/bcdef>0, abc/def>0, so on and so forth.

Statement 1: p or m could have all sorts of parities (both negatives, both positives, 1 neg + 1 pos, 1 pos + 1 neg).

Not sufficient.Statement 2: In light of our discussion above

Sufficient
