Know how to calculate the percentage of the number, it can be useful not only to high school students.In everyday life, this skill is required in order to calculate the credit payment, calculate and check whether it is true accountant calculate the amount of tax you pay on delivery.And many employees a wide variety of companies and enterprises is the ability to just need to work on.
What is it - the percentage?From school curriculum everyone remembers that the percentage of the world is considered to be one hundredth part of anything.That is, in other words, the term "percent 3" should be understood as a three-hundredths of any number.For brevity people accepted the designation of the word "percent" sign "%".
And at school we all know how to calculate the percentage of the number: the number divided by one hundred, finding the value of one percent, and then the resulting quotient is multiplied by the number indicating the amount of interest that you need to find.
For example, it is necessary to know what is 28% of 500. The reasoning shall be such as:
- find the size of 1% of the 500 division.
500 100 = 5
- find the specified number of multiplying the quotient at 100.
5 x 28 = 140.
That is, 28% of the 500 - is 28/100 of 500. Thereforeto another, you can record the action:
500 x 28/100 = 140.
So how to calculate the percentage of the number is not always easy in the mind and pen and paper at hand is not everywhere, but today many people use calculators.
For calculation you can use the method described above: a specified number divided by one hundred and multiply by the required amount of interest.
there faster opportunity count:
- the calculator entered the specified number.In our case - 500.
- Then press "multiply."
- then dials the number of the required interest - for our options is 28.
- Instead choose equality sign on the calculator%.
- obtain the result - it is 140 in this example.
And how to calculate the percentage of the number on the computer, using the settlement function in the program «Excel»?It is also a fairly simple procedure.
- in the cell that displays the calculated percentage injected an equal sign "=".Next
- recorded a predetermined number, which you need to look for a percentage or "address" of the cell, where the number is already entered.We introduce in our example the number 500.
- The third step is to sign the nomination "multiply" or "*".
- must now write down the number that represents the number of the desired percent.For us it is 28.
- penultimate step is to mark the introduction of "interest", which is kind of "%".
- To get the result you only press the keyboard button «Enter».Result - 140 - will not be slow to appear on the monitor.
Before you start the program «Excel» follows the left mouse button to put in the appropriate format table cells, or use the "menu" "Format - Cells - Numbers - interest."
opposite examples of how to calculate the percentage of the number, is the option of finding how many percent one number is of another.
For example, we are number 140 and 500. The question is thus: what percentage of 500 is 140?
- first find what is equal to one percent of the 500. That is, we go for the old scheme and divide 500 by 100. Get 5.
- Now you know how much such interest comprises a given number 140 140. To this should be divided into 5. We get the same 28 percent!
- In one formula this calculation can be written as follows:
140 (500: 100) = 140: 500/100 = 140: 500 X 100 = 28.
That is, the number of 140 500is 28 percent.
In order to find out what percentage one number is of another, we should be divided into a smaller number of larger private and multiply by 100.
These skills are critical entrepreneurs who are engaged in trade.In setting the price of goods usually requires skill, how to calculate the percentage of the number, since this action is necessary to "cheat" on the product.The most convenient way to do the same for the whole range cheat a percentage, such as 15%.
But for the calculation of net income and other needed skills.For example, the daily revenue stall was 3450 rubles.What is the net income from goods sold?Some aspiring entrepreneurs naive to calculate 15% of gross revenues, and a gross error!Withdrawn from circulation resulting in such a wrong way, "cheat", and then they sit and scratching their heads, where there was a shortage.
And everything is very simple.After cheating in the product was not present 100% of the cost, and 100% + 15% = 115%.Therefore, to find the sum of the proceeds of added value, 15% is calculated as follows:
- are 1% of revenues, not dividing it by 100, and 115. That is, in this case
3450: 115 = 20
- Anow you can search the added value that can be extracted from the brave turnover.
20 X 15 = 300
These figures are taken "from the ceiling", so do not be serious about this data.But do methods of calculating merit, they have no errors.
