Understanding Percentages
A percentage is a way of expressing a number as a fraction of 100. The term "percent" comes from the Latin "per centum," meaning "out of one hundred." Percentages are used everywhere, from calculating /blog/calculate-percentage-savings-between-two-prices to understanding /blog/body-fat-percentage-calculator readings.
