Understanding Percentages
In mathematics, a percentage represents a fraction of 100. It's a way to express the relationship between two numbers without dimensions. Other methods include ratios, fractions, and decimals. You'll often see the symbol "%" after a number to indicate percentage. For example, 35% is the same as the decimal 0.35 or the fraction 35/100.
The Percentage Formula Explained
The main formula can be expressed as:
P × V1 = V2
Where:
- P = Percentage
- V1 = The first value that the percentage will modify
- V2 = The result of the percentage operating on V1
For instance, let's say P × 30 = 1.5. To solve for P, you would do the following:
P = 1.5 / 30 = 0.05
Multiply by 100 to convert to a percentage: 0.05 × 100 = 5%
Figuring Out Percentage Difference
The percentage difference is calculated by dividing the absolute value of the difference between two numbers by the average of those numbers. Then, you multiply the result by 100 to get the percentage.
Percentage Difference = |V1 - V2| / ((V1 + V2)/2) × 100
For example:
|10 - 6| / ((10 + 6)/2) = 4 / 8 = 0.5 = 50%
Percentage Change: Increase or Decrease
To calculate percentage increase or decrease, you compute the difference between two values. Then, you compare that difference to the initial value. It involves dividing the absolute value of the difference by the initial value.
For example, if something increased by 10%:
500 × (1 + 0.1) = 550
If it decreased by 10%:
500 × (1 – 0.1) = 450
