We often use interest in everyday life: when we are counting a discount or preparing a cake. In this article, we will learn how interest problems are solved. Percentage is one of the most interesting and often used tools in practice. Percentages are partially or fully applied in any science, in any job, and even in everyday communication. A person who is well versed in percentage gives the impression of being smart and educated. In this lesson, we will learn what percentage is and what actions can be performed with it.
One of the basic concepts of mathematics is percentage. In order to understand what a percentage is, it is enough to divide a given integer value by one hundred. One hundredth will be one percent (denoted 1%). As in the exact and economic sciences, and in other areas of life, percentages are used to indicate shares in relation to the whole. In this case, the whole itself is designated as 100%. In some cases, it is used when comparing two values: for example, sometimes the cost of goods is not compared in monetary units, but it is estimated by how many% the price of one product is more or less than the price of another.
In our daily life, we are often faced with situations in which it is necessary to calculate something. This can be the determination of the amount of payments for the repayment of a consumer loan, percentage discounts in stores or the calculation of inflation. Let's figure out how you can find the percentage of a number, and also give a number of corresponding formulas with detailed examples.
There is nothing more useful in math than knowing how to calculate percentages. This will come in handy both in everyday life, when planning a budget, for example, or to check the accumulated amount on a deposit, and when writing a test paper or passing exams, so in economics there is nowhere without interest. Percentage is a very convenient way to count in the decimal system. The rule says - percentage, this is one hundredth of a number. Not necessarily hundreds. Simply, to find one percent of a particular number, you need to divide that number by 100.
