Question

A rational number can be expressed as terminating decimal if the denominator has factor s

Answer 1

Answer:

2 and 5

Explanation:

If the denominator of a rational no. has factors ONLY 2 and 5 then the no. is termination. This is because factor of 2 and 5 make up to 10 and any integer divided by 10 terminates. Even if the denominator has only $2^{x}$ or $5^{x}$ as factors still it will terminate as 5 and 2 are still present as $5^{0} and 2^{0}$ respectively. But the denominator should NOT have any other factor except of 2 and 5
