Question

How we know about the termination of any rational number

Answer 1

Answer:

If the denominator is of the form 2^n*5^m, where n & m are any two positive integers, then we can say that the fracion has a terminating expansion

Step-by-step explanation:

take the example of 50/450.

here the denominator can be writen as 2*5²*3².

we see that the denominator has 2^1 and 5², both of which satisfy the rule that the fraction has a terminating expansion
