The division problem ends A Terminating decimal The division problem goes on forever….Repeating decimal
Repeating Decimals A single digit might repeat…..3333…. Or a group of digits might repeat….275275275….
Show repeating decimals by placing a line over the digit or group of digits that repeats.33333…. Becomes.3 And.275275….becomes.275
