Repeating decimals, magic squares and conic sections

Sign up or log in to save this to your schedule and see who's attending!

We will begin by using technology to examine the period of the decimal expansion of fractions of the form 1/n, where n is a positive integer. We will establish some rules that can be used to predict the period without having to convert the fraction to decimal form. Our analysis will lead to a natural connection between certain fractions of the form 1/n and magic squares. We will end our exploration with a seemingly bizarre and stunning appearance of an ellipse and a hyperbola created from certain fractions.
