Does the decimal equivalent of P/Q, where P and Q are positive integers, contain only a finite number of nonzero digits?

(1)   P>Q 

(2)   Q=8

 


l        Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient

l        Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient

l        BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

l        EACH statement ALONE is sufficient

l        Statements (1) and (2) TOGETHER are NOT sufficient

我觉得选b,给出的答案是e
