The Mathematical Formulas Behind the Percentage Calculator
Percentage of a Number:
$$ \text{Result} = \frac{X}{100} \times Y $$Percentage Increase:
$$ \text{Increase} = \frac{\text{New} - \text{Original}}{\text{Original}} \times 100 $$Percentage Decrease:
$$ \text{Decrease} = \frac{\text{Original} - \text{New}}{\text{Original}} \times 100 $$Percentage Difference:
$$ \text{Difference} = \frac{|V_2 - V_1|}{\frac{V_1 + V_2}{2}} \times 100 $$Understanding each variable:
- X: Percentage value (e.g., 25 for 25%).
- Y: Number to calculate percentage of.
- Original: Starting value before change.
- New: Value after change.
