You will learn to Calculate Percentage of a number, article will cover explanation and examples using the percentage formula: Percentage (p) % = (x÷y) * 100, where x is the number we want to calculate percentage for, y is the original number.

What is Percentage ?

A Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, “%”.

## Calculate Percentage

**Example 1:** Find, What % is 5 of 100 ?

Placing the values in the formula. Here, % = ?, x = 5, y = 100

% = (5÷100) * 100 = 0.05 * 100 = 5 %

or

Percentage = 5 divided by 100 and the outcome of dividing multiplied by 100

**Example 2:** Find, What % is 25 of 900 ?

Placing the values in the formula. Here, % = ?, x = 25, y = 900

% = (25÷900) * 100 = 25÷9 = 2.78 %

**Conclusion:** So, the Percentage for a number can be calculated by dividing it by the original number and multiplying the reminder by 100.

## Calculate/Find number (x) based on a percentage

The same formula can be leveraged for calculating, x when a % percentage is provided.

**Example 1:** What is 20% of 100 ?

Again we will use the same formula to find x. Here, % = 20, x = ?, y= 100

20 = (x÷100) * 100

Here, we an equation, out of which we can find x = ?, so at this point the equation has 2 side, Left Hand Side (LHS) and Right Hand Side (RHS)

LHS = 20 and RHS = (x÷100) * 100

**Bonus Tips:** *Now, we just need to isolate x and move values on the other side (you may know, when moving a value from one side of the equation to other its operator changes to opposite, which is if a number is multiplying in RHS when moved to LHS it will be dividing and the other way around, same goes for addition and subtraction)*

x = (20*100)÷100

x = 20

**Example 2:** What is 35% of 9059 ?

Here, % = 35, x = ?, y = 9059

35 = (x÷9059) * 100

x = (35*9059) ÷ 100

x = 35 * 905.9

x = 3170.65

Using the Above formula and understand now you can easily calculate percentage of a number.
