Mankind has long mastered how to calculate the percentage of the amount.The word comes from the Latin «per cent», in fact, in the English language and as such it remains.«Percent» - literally "hundredth part".The name is very apt, since this concept is exactly one hundredth of the amount.If you have forgotten school science and want to understand how to get the share of the number of, say, 280,550, you just have to divide it into a hundred (or a comma in the two figures closer to the top).Thus, we get 2 805.50.And how do you know how many of the above sum will amount to three percent?Very simple: we multiply one hundredth (in this example 2 805.50) to three.It turns 8 416,50.
As you can see, very simple.If you still do not get in the mind to make the process of dividing the original numbers by 100 and multiply the result by the required amount of interest, then there is another, very simple, the way how to count the interest.As a rule, hand in modern man there is always a calculator.In most models of computing device over the buttons with the numbers there are specific icons, and one of them is the symbol "%".With this button, the process vyschityvaniya not take more than two seconds.Suppose you want to know how much will be 7% of the 550 type on the calculator 550 and then presses the button "x" (multiply), please dial 7, and then, instead of the icon "=", pressing the key "%".The scoreboard appears result: 38.5.
But sometimes we need to learn is not how to calculate the percentage of the amount, but rather what percentage one number is of another.Here's a simple example: two numbers - 1100 and 253. What percentage composes 253 of the total 1100?To calculate this we need to multiply the minimal number (253) at 100, and the result is divided by the large number (1100).23% yield.Sometimes you need to calculate the amount minus some percent.Often it concerns salaries.You know the salary, but it is interesting to know how you get on your hands, after the amount of the salary of an accountant take taxes.We collect the amount of salary on the calculator, click on the icon "-", then enter the number of hundredths of which the state collects in taxes, and click on the "%".
How to calculate the percentage of the amount, using the program Excel?In the column, where we want to deliver the desired%, you need to enter the symbol "=", and then the numbers from which we calculate the percentage, then the multiplication sign, and finally, the number of hundredths of.Then click «Enter», and the result appears in the cell.For clarity, we give an example: = 1750 *, 48,%, Enter.Before the surgery, you need to configure the program for the calculation: click on the left mouse button on a cell.
people far in their daily lives from the calculations, often bought at attractive ostensibly minor, the payments under the loan from the bank or pawn shops often get trapped.How to calculate the percentage of the loan right?We should not only arithmetically calculate the credit, but also to multiply the amount on the amount of time (days, months, years), for which it is issued.For example, you want to buy a car and take in the bank 150 thousand at 13% per annum for 5 years.How much you need to pay the financial institution during the five years?We believe: 150 000 x 13% x 5 years = 97,500 (and this is only the interest).To this sum must be added the debt itself: +150 97 500 000 = 247 500.
So do not buy into the promises of extremely low interest rates, and the need to weigh everything and calculate in your head or on the calculator.Not for nothing that the bankers in the Middle Ages developed a whole complex tables showing how to calculate the percentage of the amount granted to the borrower.These calculations were first declassified only in 1584.And by the way, did you know where it came from such an icon, indicating the percentage - "%"?He appeared in circulation only in 1685 thanks to ... simple myopia.While in Paris for students, businessmen were published "Guidelines for commercial mathematics."Typewriting overlooked and widely accepted until the end of the XVII century the symbol «cto», which refers to one hundredth of, two little toe, separated by a slash.Happened %.And since it was the textbook, the new generation of traders taken as a given icon.
