Percentage means “per 100” is helps in business and various professional settings such as when calculating taxes or employee raises. To calculate percentage multiply the number by 100. Percentage can be calculated by different components of a percentage.
What are the strategies to calculate percentage ?
The following formula is a common strategy to calculate a percentage:
- Verify the total amount :
If you want to calculate the percentage of days it rained in a month, you would use the number of days in that month as the total amount. Evaluate the amount of rain during the month of April’s 30 days. - Determine by dividing the number :
Using the example above, let’s say that it rained 15 of the 30 days in April. You would divide 15 by 30, which equals 0.5. - Multiply the digit by 100 :
You would multiply 0.5 by 100. This equals 50, which would give you the answer of 50%.
Use the following formula for the proper and easy calculation of converting a digit in percentage :
P × V1 = V2
V1 is the first value that the percentage will modify and V2 is the result of the percentage operating on V1. It provided automatically converts the input percentage into a decimal to compute the solution. You can use operating system.

Examples :
Example 25 of 200?
Solution : (25/200) × 100
Divide the numerator by denominator;
= (1/8) × 100
= (1 × 100)/8
= 100/8
= 25/2
= 12 .5 %
Percentage Difference Formula
Percentage Difference = |V1 – V2| (V1 + V2)/2 × 100
EX: |10 – 6|
(10 + 6)/2
=48
= 0.5 = 50%
