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%
