If r and s are postive integers and the r/s is expressed as a decimal, is r/s a terminating decimal?

(1) 90<r<100

(2)s=4

I think both (1) and (2) are needed to answr the question. But Power Prep says only (2) is sufficient.

But why?

answer it B...if s=4 it will be a terminating decimal...whether the no. lies between 90 -100 or 10 -20...

e.g..

lets take r as 95 thus 95/4 = 23.5 terminating

now take r as 17 thus 17/4 = 4.25 terminating...so if a no. is divided by 4 it is always going to be terminating...

hope this helps

cheers!!

Yes, agree with B... 4 as a multiplier will always yield a terminating decimal....
