Percentage Poem by Lauren Coles

Percentage
Math is part of every day life,
People know when you get down to half gallon of milk it's time to go to grocery store,
It's the same for getting gasoline,
If you are moving a piece of furniture you have to make sure that it will fit,
Because if it doesn't fit then it's a waste of money,
People use percentages to make guess on what people like to do with their free time,
I wonder what the percentage of the people who live on the planet write their thoughts down on paper.
If we knew the answer the question would be easy to answer.
