Introduction
Calculating percentages is an essential skill in mathematics, and understanding how to find a specific percentage of a given number can come in handy in various real-life situations. In this article, we will explore how to determine 20 percent of 80, step by step, using a clear explanation voice and tone.
Understanding Percentages
Before diving into the calculation, it's important to have a basic understanding of percentages. A percentage represents a fraction of 100, where 100% is equal to the whole. Therefore, when we talk about finding a certain percentage of a number, we are essentially finding a fraction of that number out of 100.
Step 1: Convert 20% to Decimal Form
The first step in determining 20 percent of 80 is to convert the percentage to decimal form. To do this, we divide the percentage by 100. In this case, 20 divided by 100 is equal to 0.20.
Step 2: Multiply the Decimal by 80
Now that we have converted 20% to decimal form, we can proceed to the next step. Multiply the decimal (0.20) by the original number, 80. This can be done by multiplying the decimal by the whole number without the percentage sign. Performing this calculation yields the result.
Calculating 20 Percent of 80
To calculate 20 percent of 80, we multiply 0.20 by 80:
20% * 80 = 0.20 * 80
= 16
Answer
Therefore, 20 percent of 80 is equal to 16. This means that if we take 20 percent of the number 80, we will end up with the value 16.
Real-Life Applications
Understanding how to calculate percentages can be useful in various real-life scenarios. For example, imagine you are shopping and come across a sale where all items are marked down by 20%. If you see an item originally priced at $80, by knowing that 20% of 80 is 16, you can quickly determine that you will save $16 on that item.
Further Examples
Let's look at a couple more examples to solidify our understanding:
Example 1:
What is 20% of 200?
To calculate this, we follow the same steps:
Step 1: Convert 20% to decimal form: 20/100 = 0.20
Step 2: Multiply the decimal by 200: 0.20 * 200 = 40
Therefore, 20 percent of 200 is equal to 40.
Example 2:
What is 20% of 50?
Again, we follow the same steps:
Step 1: Convert 20% to decimal form: 20/100 = 0.20
Step 2: Multiply the decimal by 50: 0.20 * 50 = 10
Therefore, 20 percent of 50 is equal to 10.
Conclusion
Calculating percentages is a fundamental skill that can be applied in various situations. By understanding the concept of percentages and following the steps outlined in this article, finding a specific percentage of a given number becomes a simple task. Remember, to find 20 percent of a number, convert the percentage to decimal form and multiply it by the original number. Now that you know how to calculate 20 percent of 80, you can confidently tackle similar calculations in the future.
