# 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 the symbol %

## Answer: The percentage of a number is calculated by dividing that number by the total quantity and then multiplying it with 100.

Read the steps listed below to see how to convert a number to a percentage.

**Explanation:**

- Determine the amount for which you want to find the percentage.
- Divide the number by the total quantity given.
- Multiply the result of the previous step with 100 to convert it into its 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%

### Thus, the percentage of a number is calculated by dividing that number by the total quantity and then multiplying it with 100.
