How to calculate percentages with calculator

Do you want to get a percentage with the calculator and do not know how to do it? It is very simple, and is that all calculators include a specific key to calculate the percentage and thus simplify this calculation. So stop using pencil and paper, do not wait any longer and keep reading this article to learn how to calculate percentages with a step by step calculator.

Steps to follow:

one

Although you can use a calculator of the life, in this article we will teach you to calculate percentages with the Windows calculator, in order to show you images of step by step. So, the first thing you should do is open the calculator on your computer through the Start menu.

Likewise, we will give an example to explain more clearly the best way to calculate percentages with a calculator. Suppose then that we want to calculate 20% of 150, so the first thing that we should write in the calculator will be the quantity on which we want to apply the percentage, that is, 150.

3

The next step will be to multiply the previous amount by -pressing the asterisk (*) button on the calculator or with your keyboard- the figure of the percentage you want to calculate, which in our example will be 20.

Remember then, the operation that we are formulating at the moment is: 150 * 20

And now it will be time to press the percentage key (%) that every calculator, however simple, includes. This functionality allows you to take the percentage directly, without having to perform any other operation.

In this way, following the initial example, we will have typed in our calculator:

150 * 20%

5

By pressing the percent key (%) on the calculator, we will automatically see the result of the operation on the screen, that is, we will have already calculated the percentage.

In our case, we can affirm that 20% of 150 is 30, as indicated by the calculator.

And to verify that we have made the percentage with a calculator correctly, we can do the check by doing the calculation manually. So, you must remember that calculating a percentage is equivalent to applying a rule of three.

In this way, in our example, we can say that if 100% is 150 to 20% we will give the value 'x' because we do not know how much it is worth. To clear the 'x', we will have to multiply in cross and divide between the other figure, in this case, between 100 because it is a percentage.

When multiplying 20 x 150 and dividing it by 100, we obtain that 20% of 150 is 30, the same result we obtained when calculating with the calculator. How about?
