What is the smallest positive integer \(\frac{n}{n+101}\) such that  is equal to a terminating decimal?

 

Thanks!

In order for a fraction to have a terminating decimal representation the denominator must 

have factors of only powers of 2 or 5.

 

when n=24, n+101=125 which is 53

 

This appears to be the smallest positive integer meeting the criterion.
