Hi everybody,
Since I am not a native english speaker I sometimes find hard to really figure out what a question is asking me. For instance, let's take Data Sufficiency #80 in the OG13.:
If r and s are positive integers, can the fraction r/s be expressed as a decimal with only a finite number of nonzero digits?
1) s is a factor of 100
2)r is a factor of 100
In my mind I assumed that a decimal with only a finite number of nonzero digit would look something like this : 0.45 or 0.3
But I am not sure about it because the solution at the end shows number like 0.20 0.04 or 0.02 , they all look like decimal with finite number, but shouldn't they be nonzero too?
