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




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

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

lBOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

lEACH statement ALONE is sufficient

lStatements (1) and (2) TOGETHER are NOT sufficient

答案是E 我认为是B吧！！！谢谢各位啦 ~~

题目中说non-zero，即非零的。
假设P=16，Q=8，那么小数部分就是0了；若P=20，则小数部分不是0.
所以两个条件在一起仍然不能推出。选E
