Is \(2m - 3n = 0\)? Or is \(2m = 3n\)?
1) \(2|m| = 3|n|\)
If \(m = 3 & n = 2\) YES
If \(m = -3 & n = 2\) NO
NOT SUFFICIENT
2) \(\frac{m}{n}\) is positive
Which implies that both have the same sign, both positive or both negative
Could be any set of values which could easily give us a yes and and a no
NOT SUFFICIENT
BOTH COMBINED
Both variables are the same sign so modulus of the first statement is almost irrelevant so
SUFFICIENT
