To show the group of digits that repeat in a repeating decimal, you can use a bar over the repeating digits. This is often called a "repeating bar" or a "repetition bar." By placing a bar over the digits that repeat, it visually represents that the group of digits repeats infinitely.
For example, if you have the decimal representation 0.333..., where the digit 3 repeats infinitely, you would write it as 0.3̅. The bar is placed over the digit or group of digits that repeat. The bar can be drawn either as a short horizontal line or as a curly line depending on personal preference or convention.
So, to explicitly represent the group of digits that repeat in a repeating decimal, you can use a bar over the repeating digits, rather than using italics, underlining, or parentheses.
