We'll break down the process step-by-step and provide different methods to arrive at the correct answer. Knowing how to find 20% of 800,000 is useful in various financial and business situations.

Method 1: Using the Decimal Equivalent

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

• Step 1: Convert the percentage to a decimal: 20% / 100 = 0.20

• Step 2: Multiply the decimal by the number: 0.20 * 800,000 = 160,000

Therefore, 20 percent of 800,000 is $\boxed{160,000}$.

Method 2: Fraction Method

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

• Step 1: Express the percentage as a fraction: 20% = 20/100 = 1/5

• Step 2: Multiply the fraction by the number: (1/5) * 800,000 = 160,000

Again, we find that 20 percent of 800,000 equals $\boxed{160,000}$.

Method 3: Using Proportions

This method is particularly helpful for understanding the relationship between the percentage and the whole number.

• Step 1: Set up a proportion: Let 'x' represent 20% of 800,000. The proportion would be: 20/100 = x/800,000

• Step 2: Cross-multiply: 20 * 800,000 = 100 * x

• Step 3: Solve for x: 16,000,000 = 100x => x = 16,000,000 / 100 = 160,000

Once more, the calculation confirms that 20 percent of 800,000 is $\boxed{160,000}$.
