Breaking Down the Formulas
While our calculator simplifies the process, understanding the underlying formulas can be helpful. Here's a closer look at each type of calculation:
1. Finding P percent of X
This is used to find a specific percentage of a given number. The formula is:
Y = (P/100) * X
Where:
- Y = Result
- P = Percentage
- X = Original Number
Example: What is 20% of 500?
Y = (20/100) * 500 = 100
So, 20% of 500 is 100.
2. Finding What Percent of X is Y
This is used to determine what percentage one number is of another. The formula is:
P = (Y / X) * 100
Where:
- P = Percentage
- Y = Part
- X = Whole
Example: 50 is what percent of 200?
P = (50 / 200) * 100 = 25%
So, 50 is 25% of 200.
3. Finding X if P Percent of it is Y
This is used to find the original number when you know a percentage and the result. The formula is:
X = Y / (P/100)
Where:
- X = Original Number
- Y = Result
- P = Percentage
Example: 30 is 60% of what number?
X = 30 / (60/100) = 50
So, 30 is 60% of 50.
