Percentage Formula PDF & Download
Percentage formula is the simplest form, percentage means per hundred. To express a number between zero and one, percentage formula is used. It is define as a number represented as a fraction of 100.It is donated by symbol % and is majorly used to compare and find out ratio
Although the percentage formula can be written in different forms, it is essentially an algebraic equation involving three values.
P x V1 = V2
P is the percentage, V1 is the first value that the percentage will modify, and V2 is the result of the percentage operating on V1. The calculator provided automatically converts the input percentage into a decimal to compute the solution. However, if solving for the percentage the value returned will be the actual percentage, not its decimal representation
Percentage Difference Formula
The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by 100 will yield the solution in percent, rather than decimal form. Refer to the equation below for clarification.
Use the percentage formula: P% * X = Y
- Convert the problem to an equation using the percentage formula: P% * X = Y.
- P is 10%, X is 150, so the equation is 10% * 150 = Y.
- Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Example – 1
What number is 2% of 50 ?
This is just another way of saying 2% of 50 is ___
So, set up the proportion as example #1:
is/50 = 2/100
Replace is by y and cross multiply to get:
y × 100 = 50 × 2
y × 100 = 100
Since 1 × 100 = 100, y = 1
Therefore, 1 is 2 % of 50
