A repeating decimal or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating (i.e. all except finitely many digits are zero). For example, the decimal representation of 1/3 becomes periodic just after the decimal point, repeating the single digit "3" forever, i.e. 0.3… WebApproximating a fraction with periodic decimal expansion by a finite decimal fraction. For example, 5/3 by 1.6667. Replacing a rational number by a fraction with smaller numerator and denominator. For example, 3122/9417 by 1/3. Replacing a fractional decimal number by one with fewer digits. For example, 2.1784 dollars by 2.18 dollars.
