Answer 7

The correct way to show the group of digits that repeat in a repeating decimal is by putting a bar over them. This bar is called a vinculum. So, if you have a repeating decimal like 0.333..., the repeating digit(s) can be shown as 0.3̅. Similarly, if you have a repeating decimal like 0.123123123..., the repeating digit(s) can be shown as 0.123̅.
