When the denominator of a rational number is in the form 2n x 5m
The decimal expansion terminates after n places if n>m or after m places if m>n
So,
will terminate after 4 places of decimals since 4>3
As the denominator of next rational number is 23 x 54 x 32
It has factors other than 2 and 5 which is 3.
So, its decimal expansion will be non-terminating and repeating.
