Answer:
Option A.
Step-by-step explanation:
The given number is
\(\frac{9}{11}\)
\(\frac{9}{11}=0.8181818..\)
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: \(2.3333..=2.\overline {3}\) and \(4.381381..=4.\overline {381}\)
Using recurring notation the given expression can be written as
\(\frac{9}{11}=0.\oveline{81}\)
Therefore, the correct option is A.
