Concerning this problem, one in which you are tasked with finding the fraction of a number with repeating decimals, there are not really many things one has to remember to do. Though, it is a bit important that one remember to add whatever you didn't account for in your geometric series. In my case, it was the 4, since it was not part of the repeating numbers. You must also remember to plug your answer back in, to see whether or not you did it correctly. I mean, you don't really have to, but it is quite useful for saving a bit of face when having your problem examined by your colleagues. Yep.
