Let x=pq be a rational number, such that the prime factorisation of q is of the form 2n5m, where n, m are non-negative integers. Then, x has a decimal expansion which terminates.What does this mean?

I assume x = p/q where p and q are integers
If q = 2n 5m , where n and m are integers, .  then p is divided by 2 and 5   or p is divided by 10.
If an integer is divided by 10, we will get terminated decimal fraction, not a recurring decimal fraction
