If x and y are positive integers, does \(\frac{x}{y} = \frac{7}{9}\)?
(1) \(x = 103\)
Now \(\frac{x}{y} = \frac{7}{9}\) means x HAS to be a multiple of 7, but 103 is NOT a multiple of 7, hence answer is NO
Suff
(2) \(\frac{11}{13} < \frac{x}{y} < \frac{8}{9}\)...
Now \(\frac{7}{9}<\frac{11}{13} < \frac{x}{y} < \frac{8}{9}\)...
So again answer is NO
sufficient
