Rational NumbersA Recipe for Success

On May 15, 2005, a group of volunteers met in Las Vegas to create what would become the world's largest cake. In order for the cake to qualify for the Guinness Book of World Records, it had to meet the following qualifications:

contain traditional ingredients in the correct proportions,be prepared in the same manner as a normal­sized cake,be prepared according to appropriate hygiene standards, andbe totally edible and safe to eat.

To create the world's largest cake, the organizers had to begin with a recipe for one cake and scale the ingredients accordingly. A sample recipe for one cake is shown below.
