Said differently, when a fraction is expressed in decimal form but always has a remainder regardless how far the long division process is carried through, the resultant decimal is a non-terminating decimal.. Non-terminating, terminating, and repeating decimals To find the decimal expansion, you "unexplode" dots, form groups of six, see how many dots are left, and repeat. Hence, the decimal expansion is terminating. 1 Answer. For example, π is an irrational number and π = 3 . Q. How should a rational number's decimal expansion be done? Such types of decimal expansion are called terminating decimals. Since the denominator is not in form of 2 m × 5 n, and it also contains 7 and 13 as its factors, its decimal expansion will be non-terminating repeating . The correct option is D. 3 11.
