And use it to find out what kind of fraction denominator various numbers make. For example, 3, as a denominator makes a repeating decimal. 7 does too, but it is more than one number before the pattern repeats. The program asks you how many places after the decimal point you wish to solve to. These are the screen prompts:

Solve 1/n to how many places? [the numerator is 1 because, if it is a repeating decimal, the answer will be a multiple of the 1/n answer.]

Enter your denominator:

At this point, the program will give you the prime factors of the denominator, then it will solve the problem to however many places you desire.

You have two choices:

1. Make a list of denominators which generate repeating decimals which repeat 1 numeral, then 2 numerals, then 3 numerals, etc. until you have a list of 10 denominators, the last of which contains a series of ten digits before it repeats. Be sure to explain how you chose your numbers.

or
2. Find a denominator which does not appear to repeat in the first 100 places.. Be sure to explain how you chose your numbers.

This is due no later than end of class on 29 January and is worth from 3 to 5 extra credits. Work from now until January 29 must be kept current.
