How do you show that a decimal is repeating?

Answer 1

To show that a decimal number is of a repeating nature, simply insert a horizontal bar over the numerals that are repeating. When typing, you may also underline the repeating digits or place them in parentheses.

A few examples:

1/3 = 0.33333333 = 0.(3)

1/6 = 0.16666666 = 0.1(6)

1/11 = 0.09090909 = 0.(09)

1/24 = 0.04166666 = 0.041(6)
