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.
- 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
By formula we have,
Value = 20, Total quantity = 50
Percentage = (20/50) × 100
