An important basic concept in mathematics is considered to be a percentage. It is used in economic disciplines and sciences, when calculating contributions and taxes, and is often used as a synonym for the concept of interest rate. The concept means shares in relation to the whole, which is taken as 100%. Sometimes the percentage is important for comparing two values: in the cost of goods, it is often estimated by which % the price of the first product is higher or lower than the cost of the second.
