Question

Answer 1

Answer:note that ,the rational number whose denominator is in the form (2^m×5^n) ,then it will be terminating decimal, otherwise it will be no terminating decimal.

we have the rational number as 11/18.

the denominator can be written as,

18=2×3^2

which is not in the form 2^m×5^n

thus is non terminating decimal.
