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

答案选择E，但是我选择B，逻辑如下

P/Q = (1/Q)*P

而若Q=8，则1/Q = 0.125

那么无论P是什么positive integer，(1/Q)*P都由有限的数字组成

请指教，谢谢。

我选C,难道0.125中的"0"是"nonzero digit"么?

contain only a finite number of nonzero digits

包含有限数量的非0数字，所以0.125有三个非0数字。
