17-Q32:

Does the decimal equivalent of p/qATH connecttype="rect" gradientshapeok="t" extrusionok="f">ATH>, where p and q are positive integers, contain only a finite number of nonzero digits?

(1) p > q

(2) q = 8

Key is B???

-----------------------------

P 未定,怎么only a finite number.....?

这道题的意思是小数部分是否是非零位有限小数。1-8后的数除以8与1-8除以8小数部分

是循环的。比如9/8和1/8小数部分是相同的。
