Percentages Everywhere
Percentages are used in almost every part of daily life: from shopping discounts and credit card interest to statistics, nutrition labels, and sports scores.
The Logic Behind
The Formula
To calculate the percentage change between two values, subtract the original value from the new value, divide the result by the original value, and then multiply by 100.
Common Scenarios
Price Increase
$80 → $100
Discount Applied
$200 → $150
Website Traffic
1,200 → 1,500
Weight Loss
90kg → 81kg
Negative Percentages Exist Too
Percentages aren’t just for gains—they can represent decreases or losses as well. For example, a 20% discount on a product or a 5% drop in profits can be easily understood using percentages.
