A repeating decimal is a periodic decimal representation expressed as a fraction. For example, the decimal number 0.3333… can be represented as the fraction 1/3. The notation “…” indicates the infinite repetition of a block of digits.
In general, a repeating decimal takes the form a/b, where ‘a’ is the non-repeating part and ‘b’ is the repeating block.
This method is useful for precisely and concisely expressing decimal numbers using fractions.
