MGMAT question

by ankur.agrawal » Tue Mar 22, 2011 8:42 am
Any decimal that has only a finite number of nonzero digits is a terminating decimal. For example, 36, 0.72, and 3.005 are terminating decimals.
If a, b, c, d and e are non-negative integers and p = 2^a *3^b and q = 2^c*3^d *5^e, is p/q a terminating decimal?

(1) a > c

(2) b > d

I was going through some earlier posts just now & found a similar kind of problem .

Anurag explained it pretty well:

"A fraction will always be a terminating decimal if in its reduced form it has a denominator with only 2 or 5 as its prime factors."

This statement alone is sufficient to deal with these kind of problems.

Thanks I got it.
