State whether following rational number have terminating decimal expansion or not and if it has terminating decimal expansion, find it:
![]()
Convert the given rational number into lowest divisible terms.
If the denominator is in the power of 2 OR/AND 5, then the given number is terminating else non- terminating.
Prime factorization of 343 = 7 × 7 × 7
i.e. it is not in the power of 5 & 2
So, the given rational number is non- terminating in nature.
