Answer 2

Answer: Option c) 63/90

Explanation :- Read the question. If the denominator has only factors of 2 and 5 or in the form of 2m ×5n then it has terminating decimal expansion. If the denominator has factors other than 2 and 5 then it has a non-terminating decimal expansion. Since, the denominator has only 5 as its factor, 63/90 have a terminating decimal expansion
