The correct answer is by putting a bar over them.
To show the group of digits that repeat in a repeating decimal, you put a horizontal line or bar over the digits that repeat. This is typically done when writing the decimal representation of the repeating pattern.
For example, if you have the decimal 0.333333..., the repeating digit is 3. To indicate this, you would write it as 0.3̅.
So, when encountering a repeating decimal, remember to indicate the repeating group of digits by placing a bar over them.
