    Since you have answer choices given, you can take a calculator and divide each choice and see which one it is.

    we have to apply this rule: \[\Large 0.\bar 5 = \frac{{5 - 0}}{9} = ...\]

    If you will face a similar question without choices, then you need to learn how to convert a non-terminating, repeating decimal into a fraction in a proper way.

    \(\large \dfrac{5}{10} = 0.5\) non-repeating

    here is the rule, let's suppose to have this periodic number: \[\Large 1.25\bar 4 = 1.2544444444....\] then we can rewrite it as follows: \[\Large \frac{{1254 - 125}}{{900}}\]

    the periodic number is equal to a fraction, whose: numerator is the difference between the complete number and its part which have not an overbar denominator is composed by one 9 for each figure with a bar, and one zero for each figure before the figure with the bar, and after the decimal point @nuccioreggie @mathstudent55
