Legal Definition
Percent is a measure of the relative size or proportion of a part to a whole, expressed as a ratio, often used in financial, statistical, or contractual contexts to quantify a relationship or rate.
Plain-English Translation
It means a fraction of a whole thing. If you have 100 pieces, and 'percent' tells you how many pieces that is out of 100, like 25 percent means 25 pieces out of 100 total.
