I think this is a very simple question. In order to know the answer we simply need to know the values of r and s. 1) gives us only s, not sufficient. 2) only r, not sufficient. Both 1) and 2) give the required answer. It's basically a no-brainer. Since this is a data sufficiency, there is no need to actually calculate and give the answer whether it is or isn't a terminating decimal, but we know that by having two values we will be able to find that out.

I think this is a high-quality question and I agree with explanation. Many thanks Bunuel, very helpful. When we say that the denominator must be 2^n*5^m, with m,n being non negative integers, this includes zero as a non negative integer right? which would translate the power into "1".

thanks a lot

Hi,

Right. If n = 0 or/and m = 0, then integer/2^n*5^m will be terminating. And yes, if both are 0, then we'd get integer/1, which is also a terminating decimal.
