For example, if you want to find what percentage 25 is of 100, the formula would be (25 / 100) * 100 = 25%.
Percentage Increase and Decrease
Understanding percentage increase and decrease is crucial in various situations, like tracking investment growth or sale discounts.
- Percentage Increase: To calculate the calculate percentage increase, use the formula: ((New Value - Original Value) / Original Value) * 100
- Percentage Decrease: To find the percentage decrease, use: ((Original Value - New Value) / Original Value) * 100
Imagine a product's price increased from $50 to $60. The percentage increase is (($60 - $50) / $50) * 100 = 20%
