Understanding Percentages
Percentages are a way to express a number as a fraction of 100. They are widely used in finance, science, and everyday life to describe proportions, changes, and distributions.
Practical Examples
- Sales Tax: If an item costs $50 and the tax is 8%, you calculate 8% of $50 ($4) and add it to the total.
- Discounts: A "20% off" sale means you pay 80% of the original price.
- Growth: If your savings grew from $1,000 to $1,050, that's a 5% increase.
