Answer Key
The decimal expansion of the fractions where the denominator is not a power of ten nor one of the 'easy' numbers has been rounded to 8 decimals, so it may or may not show the repeating pattern for non-terminating decimals, and it may or may not show all the decimal digits for terminating decimals.
