This one is an intermediate challenge. I had to have quite a bit of help on it. I also had to crte a break line that resets the fraction to 3/1 because it kept freezing up on me. well it is finished anyway. I also figured out that in order to get a float from two ints you have to divide them as floats. makes sense in hind sight.

#a list of rational approximations of Pi. Output should look like:
