Answer:
Consider,
x – rational number whose decimal expansion terminates.
Express x in the form ????/????, where a and b are coprime
Prime factorization of b is of the form (2m × 5n) [m and n – non-negative integers]
If the rational number a/b has a terminating decimal expansion, what is the condition to be satisfied by b?
