Percentage Calculator

In the world of math, percentage is like a unique way to show a part of something compared to a whole, and it always involves the number 100. It's usually said as "Out of hundred", that's what we are talking about. You've probably seen it as the symbol "%". For instance, 35% is the same as saying 0.35 differently, or you can think of it as 35 out of hundred.

To calculate percentages, you take a ratio and make it look like something out of 100; as the simple fraction is written. Let's say in a classroom, 25 out of 50 students are boys. That's a ratio of 25 out of 50, which is the same as 0.5. Now, when we multiply 0.5 by 100, we get 50. We can say that 25 boys out of 50 students means that 50% of the students in the class are boys.

Percentage Formula

The percentage formula may look different sometimes, but it's actually a math equation with three things involved.

P x V1 = V2

P stands for the percentage, V1 is the first number you want to change with the percentage, and V2 is the answer you get after using the percentage on V1. The calculator changes the percentage you put into a particular number to solve the problem. But if you want to find the percentage itself, the number you get will be the actual percentage, not the special one. For example, if you have P times 60 equals 3, you can find P by using the method below.

P = 3 / 60 = 0.05 x 100 = 5%

If you're doing this without a calculator, you need the percentage in that particular form. So, you have to multiply the answer for P by 100 to make it a percentage. That's what the calculator does, but it's good because it can work with percentages instead of the particular form.

Now, there's another formula for finding the percentage difference between two numbers. You can do this by taking the difference between the two numbers, making it positive and then dividing it by the average of the two numbers. After that, you multiply the answer by 100 to get it in percentage form.

Percentage Difference =

       |V1 - V2|

      (V1 + V2)/2

 x 100
