In the last article, we learned how to turn simple repeating decimal numbers into fractions. Specifically, we learned how to convert decimals in which the same number repeats over and over again starting right after the decimal point. Our goal in that article was to understand how to convert simple repeating decimals to fractions. In particular, we looked at decimals like 0. The quick and dirty rule we discovered is that these types of repeating decimals are equivalent to the fraction that has the number doing the repeating in its numerator and the number 9 in its denominator. But what about decimals that have a whole pattern of repeating digits instead of one single repeating number—something like 0. To figure out how to convert a decimal like 0.
