i got a less-than-satisfactory grade on a test today(less than satisfactory in my parents eyes, at least, its an 80%...) and the teacher offered a 10% extra credit assignment for everyone.
ive done all of it, but there is one problem that is really getting me...
i wouldnt normally ask on such an assignment, but its all or nothing, and my calculator doesnt go high enough to figure it out for sure.
What fraction is exactly equal to .9(repeating)?
note: CANNOT be .9repeating over 1.
thanks in advance
