Understanding Percentages

Before we dive into the calculation, let's refresh our understanding of percentages. A percentage is a fraction of 100. So, 30% means 30 out of 100, or 30/100. We can simplify this fraction to 3/10.

Calculating 30% of 6: Two Methods

There are two main ways to calculate 30% of 6:

Method 1: Using Decimal Conversion

Convert the percentage to a decimal: Divide the percentage by 100. 30% divided by 100 is 0.30 (or simply 0.3).
Multiply the decimal by the number: Multiply 0.3 by 6. 0.3 * 6 = 1.8

Therefore, 30% of 6 is $\boxed{1.8}$

Method 2: Using Fractions

Convert the percentage to a fraction: As mentioned earlier, 30% is equal to 30/100, which simplifies to 3/10.
Multiply the fraction by the number: Multiply 3/10 by 6. This can be written as (3/10) * 6 or (3 * 6) / 10.
Simplify: (3 * 6) / 10 = 18/10 = 1.8

Again, we find that 30% of 6 is $\boxed{1.8}$

Practical Applications

Understanding percentage calculations is crucial in many real-world situations:

Sales and discounts: Calculating discounts in stores.
Finance: Determining interest rates or tax amounts.
Statistics: Analyzing data and interpreting results.
Everyday life: Calculating tips, splitting bills, or understanding proportions.
