Repeating decimal representations

Some real numbers have decimal expansions that eventually get into loops, endlessly repeating a sequence of one or more digits:
:1/3 = 0.33333...
:1/7 = 0.142857142857...
:1318/185 = 7.1243243243...Every time this happens the number is still a rational number (i.e. can alternatively be represented as a ratio
