A percentage is a proportion expressed as a fraction of 100. It is often denoted using the percent sign, "%", or sometimes as "pct." For example, 45% (read as "forty-five percent") is equal to 45/100, or 0.45.
How Do We Use Percentages in Real Life?
Percentages are used every day in many ways. Here are some examples:
- An item that was originally priced at $100 is now on sale for 20% off. The new price is $100 × (1 - 0.20), or $80.
- A bill comes to $103.50 after tax. The sales tax rate is 6%. The amount of sales tax paid is $103.50 × 0.06, or $6.21.
What Is the Formula for Percentage?
Percentage = (Part / Whole) × 100
