Answer:
Option A.
Step-by-step explanation:
The given number is
[tex]\frac{9}{11}[/tex]
[tex]\frac{9}{11}=0.8181818..[/tex]
A repeating or recurring decimal exists when decimal numbers or pair of decimal number repeat forever. It is represented by overline above the reprinting numbers.
For example: [tex]2.3333..=2.\overline {3}[/tex] and [tex]4.381381..=4.\overline {381}[/tex]
Using recurring notation the given expression can be written as
[tex]\frac{9}{11}=0.\oveline{81}[/tex]
Therefore, the correct option is A.
