                        To determine what power of 10 you will need, count the number of digits
                        behind each decimal point.
                             1:28     Two digits behind the decimal point
                              4:6     One digit behind the decimal point

                                                          1:28   100  128   32

                        You will need to use 10 ¼ 100.             ¼     ¼
