From the image, the question asks you to write $\frac{13}{9}$ as a decimal, and if necessary, use a bar to indicate repeating digits. Let me explain this:

Step-by-Step Solution:

1. $13 \div 9$ gives $1.4444\ldots$, where the digit "4" repeats indefinitely.
2. To represent this as a decimal, write $1.\overline{4}$, where the bar indicates that the "4" repeats.

Final Answer:

$1.\overline{4}$
