In mathematics, any number or ratio that can be represented as a fraction of the whole part that is ‘100’ can be defined as the percentage of a given number. In order to calculate percentage of a given number, you should divide the number by the total number given (whole) and then multiply it by the number 100. The term percentage basically signifies per 100, hence it means a part that belongs to 100 which is denoted by the symbol of %. For example, 50 percent of a number is equal to ½ of the fraction. The term percentage is also known as a number without dimension or a dimensional number. In this article, we will try to understand some basic concepts related to percentages such as, how to calculate, related examples, and some points to remember and do a detailed analysis about them.

How to Calculate Percentage?
As mentioned above, percentage can be defined as the number which can be represented in the form of a fraction of a whole number. The following points mentioned below analyses the steps through which can calculate the percentage. Some of the steps are mentioned below;
- In order to calculate the percentage of a number, you may use the formula for it.
- The formula for calculation percentage is given by, percentage of a given number= Y, where ‘y’ is the percentage which is required.
- Now, a percentage of 100 multiplied by the number given is equal to = Y
Let us take the help of an example, in order to understand the concept in a better way.
Example 1: Calculate the 20 percent of 80?
Given that, given percentage = 20 percent.
Now, let the 20 percent of 80 be = Y
Thus, 20/100 * 80 = 16.
Therefore, Y is = 16.
Example 2: Calculate the 20 percent of 100?
Given percentage = 20 percent.
Now, let the 20 percent of 100 be = Y
Thus, 20/100 * 100 = 20.
Therefore, Y is = 20
Some Significant Facts to Remember about Percentage
The following points mentioned below analyses the significant facts about percentage. Some of them are mentioned below.
- We can define the percentage as the increase or decrease in the quantity.
- You should also remember that the fractions can be converted to percentages and percentages to fractions.
- The term percentage is also considered reversible. For example, if you calculate the 25 percent of 40, the answer will be the same as 40 percent of 25.
How to Calculate Percentage Increase and Percentage Decrease?
If you want to calculate percentage increase and decrease, you must know the formula for it. For percentage increase, the formula given is, increased – decreased value multiplied by 100. Similarly, the formula given for percentage decrease is original value – decreased value divided by original value multiplied by 100.
