The given question asks to convert the fraction \( \frac{4}{9} \) into its decimal form, and if necessary, use a bar to indicate repeating digits.

Let's perform the division of 4 by 9:

\[
4 \div 9 = 0.4444\ldots
\]

The digit 4 repeats indefinitely, so the decimal representation of \( \frac{4}{9} \) is:

\[
0.\overline{4}
\]

The bar (overline) is placed over the repeating digit 4 to indicate that it repeats infinitely.

Here are 5 related questions to expand your understanding:
1. How can you convert any fraction to a decimal?
2. What is a repeating decimal, and how do you represent it?
3. How can you identify if a decimal is terminating or repeating?
4. What are some examples of fractions with non-repeating decimals?
5. Can repeating decimals always be written as fractions?

**Tip**: You can always determine if a fraction results in a repeating decimal by checking the denominator—if it has factors other than 2 and 5, the decimal will repeat.

Write 4/9 as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats.

Learn how to convert the fraction 4/9 into its decimal form. This example demonstrates the use of repeating decimal notation, where 0.4 with a bar indicates that the digit 4 repeats indefinitely. Suitable for students in Grades 6-8.
