Answer
$0.\overline{5} = \frac{5}{9}$
Work Step by Step
RECALL:
The repeating decimal $0.\overline{a}$, where $a$ is an integer between 0 and 10, is equal to $\frac{a}{9}$
Thus, the given repeating decimal when expressed as a quotient of two integers in lowest terms is:
$0.\overline{5} = \frac{5}{9}$
