This document discusses different ways to write percentages as fractions, decimals, and the relationship between percents and pennies. It explains that any percent can be written as a fraction over 100 and then simplified. Decimals are obtained by writing the percent over 100 as a fraction and dividing, or simply moving the decimal point two places to the left. The key is that "per" means divide and "cent" refers to 100 pennies in a dollar.
