Repeating Decimals
Repeating decimals occur when a decimal representation of a fraction has one or more digits that repeat indefinitely. For example, 5/9 converts to 0.555..., where '5' repeats. Bar notation is used to denote this repetition, such as 0.5̅, indicating that the '5' continues infinitely.

Rounding Decimals
Rounding decimals involves adjusting the decimal to a specified number of places, which simplifies the number while maintaining its value. When rounding to the nearest thousandth, you look at the digit in the fourth decimal place to determine whether to round up or down. This is essential for providing a concise answer when dealing with repeating decimals.
