Without actual division, show that each of the following rational numbers is a non-terminating repeating decimal:
(vii)
Solution:
When the denominator of a fraction has a factor other than the factors of the form (Where ‘m’ and ‘n’ are positive integers), then rational numbers is a non-terminating repeating decimal.
For the given rational number, we will factorize numerator and denominator as follow,
As the denominator has the factors other than the factors of the form .
Therefore, is a non-terminating repeating decimal.
