Percent

A percent is a way of expressing a number as a fraction of 100, denoted by the symbol %. It is used to compare ratios and proportions. For example, 50% means 50 out of 100, or half. Percentages are widely used in various fields, including finance, statistics, and everyday calculations, to express increases, decreases, and comparisons. For instance, if an item originally costs $100 and is on sale for 20% off, the discount is $20, making the sale price $80.
