Decimal equivalent

[gmat009]

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

OA E, IMO B.
Plz. explain

I agree, OA should be B

Any integer when divided by 8, will be a terminating decimal.

[schakiiieee]

IMHO B as well.

Well,consider this

To find whether a fraction is terminating or not
1.Prime factorize the denominator
2.If there is a prime factor besides 2 or 5 in the denominator,the fraction represents a recurring decimal..

As per statement 2
q=8..and it contains only prime factor 2

Hence this information is sufficient to prove that the given fraction contains only a finite number of non zero digits
