which of these non terminating decimals can be converted into a rational number? .818118111 .020304050 .010110111 .321321321

OpenStudy (steve816):

Hey there! A rational number usually has some kind of patter. As you can see .321321321 repeats in the same pattern, and that decimal would be equal to\[\Large \frac{ 321 }{999 }\]
