Division by 7-recurring decimal.

by tejal777 Mon May 04, 2009 8:48 am

My vague memory tells me that there is a rule when a no. is divided by 7..there is a certain pattern in which it reccurs.Can somebody please explain?(we know that dividing a no. by 3 or 11 always produces recurring decimals.)But with 7 there is a pattern.Any help?

Hi, please post this question in the General Math folder. I would move the post for you, but the moderator tools are having a temper tantrum right now and refuse to cooperate. :)
