Discount Amount = Original Price × (20 ÷ 100)

#### 2.2: Steps to Calculate 20 Percent Off a Number

### Examples of Finding 20 Percent Off a Number

To better understand the process of finding 20 percent off a number, let’s look at some examples.

#### Example 1: Original Price: \$50

1. Write down the original price: \$50
2. Divide 20 by 100 to find the decimal equivalent: 0.2
3. Multiply the original price by 0.2: \$50 × 0.2 = \$10
4. Subtract the discount amount from the original price: \$50 – \$10 = \$40 Final Price: \$40

#### Example 2: Original Price: \$150

1. Write down the original price: \$150
2. Divide 20 by 100 to find the decimal equivalent: 0.2
3. Multiply the original price by 0.2: \$150 × 0.2 = \$30

At the end of this comprehensive guide, here are ten frequently asked questions about finding 20 percent off a number.

#### Q: How do I find 20 percent off a number without using a calculator?

#### Q: How can I find the percentage off for other numbers besides 20 percent?

A: To find a different percentage off a number, first divide the percentage by 100 to get the decimal equivalent. Then multiply the original price by the decimal equivalent to find the discount amount. Finally, subtract the discount amount from the original price to find the final price.

#### Q: Can I use this method to find the percentage increase as well?
