A recurring decimal is a type of decimal number that never ends. It keeps repeating itself over and over again. It is like a pattern or a song that repeats itself. For example 0.333 is a recurring decimal because it repeats itself three times, 0.33333 repeats five times, and 0.33333333 repeats eight times. So if you write a recurring decimal, it will just keep repeating over and over and never stop.
