Q1 of 128 Page 20

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 128 = 2 × 2 × 2 × 2 × 2 × 2 × 2 = 27


i.e. it is in the power of 2.


So, the given rational number is terminating in nature .
