Calculate 20% Now! →The Basic Formula
The easiest way to find 20 percent of a number is to use the following formula:
Result = Number × 0.20
This works because 20 percent is equivalent to 0.20 in decimal form. Let's look at some examples.
Examples of Finding 20 Percent
- What is 20% of 50? Result = 50 × 0.20 = 10
- What is 20% of 100? Result = 100 × 0.20 = 20
- What is 20% of 250? Result = 250 × 0.20 = 50
As you can see, finding 20 percent is straightforward once you understand the formula.
Alternative Methods
While multiplying by 0.20 is efficient, there are other ways to think about it:
- Divide by 5: Since 20% is one-fifth, you can simply divide the number by 5. For example, 20% of 60 is 60 / 5 = 12.
- Find 10% and Double: First, find 10% of the number (divide by 10), then double it. For example, 10% of 80 is 8, so 20% of 80 is 8 × 2 = 16.
Real-World Applications
Finding 20 percent of a number has many practical uses:
- Discounts: Calculate a 20% discount on an item's price.
