A repeating decimal is a type of decimal number that has a pattern of digits that repeats over and over again.
For example, the decimal 0.3333... is a repeating decimal. The three dots (...) mean that the pattern of the number 3 repeats forever.
Another example is the decimal 0.666..., which means the pattern of the number 6 repeats forever.
Repeating decimals can be a fun and interesting way to represent numbers, especially when the pattern of digits is easy to see and understand. And the good news is that repeating decimals can be easily converted into fractions, which can help us understand them even better!
