Question

When writing a fraction as a repeating decimal, what do we use to indicate the repeating digits? 1) Dot (.) 2) Bar (⎼) 3) Parentheses (() 4) Exclamation mark (!)

Answer 1

A bar (overline) is used to indicate the repeating digits when writing a fraction as a repeating decimal. The bar is placed over the repeating digits to show that they continue infinitely.

Step-by-step explanation:

When writing a fraction as a repeating decimal, we use a bar (overline) to indicate the repeating digits. Thus, the correct answer to the question is option 2) Bar (⎼).

The process of converting a fraction to a repeating decimal involves division, where sometimes the remainder repeats itself after a certain point. This repeating sequence of digits is the part that is represented by a bar on top. For example, the fraction 1/3 can be written as 0.3 with a bar over the 3 to indicate that the 3 repeats indefinitely.
