Any decimal that has only a finite number of nonzero digits is a terminating decimal. For. Ex. 24, 0.786, and 0.98 are three terminating decimals. If R and S are positive intergers and the ratio R/S is expressied as a decimal, is R/S a terminating decimal?
1. 90<R<100
2. S=4

seems simple. but struggled.

Straight C.
(1) don't know S
(2) don't know R
You need to know that anything divide by 5 or 2 or both or multiple of both will be terminating decimal. 4=2*2.

As you state if anything divided by 5 or 2 or both or multiple of both will be terminating decimal, then Statement 2 should be enough. We do not need to know the value of R. So, "B".

PS: Edited. Should've said 2 and not 3.

You are absolutely right. I did it too fast without thinking.
The answer must be B.

Do you mean anything divided by 5 or 2? not 3 right? Thanks, I just wanted to make sure..
