# How do I figure out a percentage of a number?

Percentage is a ratio of a number expressed out of 100. It is denoted with %

## Answer: Percentage of a number is calculated by dividing that number by the total quantity multiplied with 100

Below are the steps listed to convert a number to its respective percentage

## Explanation:

- Determine the total amount out of which you want to find the percentage for.
- Divide the number out of total for which the percentage is to be calculated.
- Multiply the result of the previous step with 100 to convert it into its respective percentage.

Thus, we can say that,

**Percentage of a value = (Value / Total quantity) × 100**

Example: Calculate the percentage of marks obtained for 20 out of 50 marks

Step 1: Total marks = 50

Step 2: Percentage to be calculated for 20 out of 50

=> 20/50 = 2/5

Step 3: Multiply the result of step 2 with 100

=> (2/5) × 100

=> 40%

By formula we have,

Value = 20, Total quantity = 50

Percentage = (20/50) × 100

= 40%
