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。
