Understanding Percentages

A percentage is a fraction or ratio expressed as a number out of 100. For example, 5 percent (written as 5%) means 5 out of every 100. To calculate a percentage of a number, you need to convert the percentage to a decimal and then multiply.

Method 1: Converting to a Decimal

The most straightforward method involves converting the percentage to its decimal equivalent. To do this, divide the percentage by 100.

Step 1: Convert the percentage to a decimal: 5% / 100 = 0.05
Step 2: Multiply the decimal by the number: 0.05 * 80,000 = 4,000

Therefore, 5% of 80,000 is $\boxed{4,000}$ .

Method 2: Using Fractions

Percentages can also be expressed as fractions. 5% is equivalent to the fraction 5/100, which simplifies to 1/20.

Step 1: Express the percentage as a fraction: 5% = 5/100 = 1/20
Step 2: Multiply the fraction by the number: (1/20) * 80,000 = 4,000

Again, the answer is $\boxed{4,000}$ .

Method 3: Proportions

You can solve this using proportions. Set up a proportion where x represents the unknown value (5% of 80,000):

x/80,000 = 5/100

Cross-multiply and solve for x:

100x = 400,000
x = 400,000 / 100 = 4,000

The result remains $\boxed{4,000}$ .
