Answer:

ab can be represented in a terminating decimal representation only if by multiplying both the numerator and denominator by some whole number n, you can get

ab=n×an×b=n×a10k

⟹n×b=10k

⟹n=10kb

⟹n=2k×5kb

Since n is a positive integer, 2 and/or 5 can be the only prime factors of b.

So we have our answer -

ab can be represented in a terminating decimal representation only if b=2p×5q, where p and q are non-negative integers, including zero
