When it comes to percentages, many people find themselves scratching their heads when trying to calculate what percentage of one number is another. If you’ve ever found yourself asking, “What percentage of 20 is 13?” you’re not alone. In this comprehensive article, we will break down the steps to calculate this percentage and provide helpful examples to guide you through the process.
Understanding Percentages
Before we dive into the specific calculation of what percentage of 20 is 13, it’s important to have a solid understanding of percentages. A percentage is a number or ratio expressed as a fraction of 100, which represents a portion out of a whole. For example, 50% represents 50 out of 100, or half of the total amount.
In the case of our question, “What percentage of 20 is 13?”, we are essentially asking how many times 13 can fit into 20, expressed as a percentage.
Calculating the Percentage
Calculating the percentage of one number in relation to another is a simple process that involves basic division and multiplication. The formula for calculating a percentage is:
Percentage = (Part/Whole) x 100
In the case of determining what percentage 13 is of 20, we can plug these values into the formula to solve for the percentage.
Percentage = (13/20) x 100
Now, let’s break down the steps to calculate the percentage in more detail:
- Identify the Part and the Whole: In our scenario, 13 is the part and 20 is the whole.
- Divide the Part by the Whole: Divide 13 by 20.
- Multiply the Result by 100: After dividing, multiply the resulting decimal by 100 to express the answer as a percentage.
Applying the Formula
Let’s go through the steps and apply the formula to calculate what percentage of 20 is 13.
- Identify the Part and the Whole: Part = 13, Whole = 20
- Divide the Part by the Whole: 13 ÷ 20 = 0.65
- Multiply the Result by 100: 0.65 x 100 = 65%
So, the answer to “What percentage of 20 is 13?” is 65%. This means that 13 is equal to 65% of 20.
Using the Percentage in Real-Life Scenarios
Understanding percentages and being able to calculate them can be extremely useful in various real-life situations. Whether you’re analyzing data, working with financial numbers, or even just trying to figure out a sale discount, knowing how to calculate percentages is a valuable skill.
For example, if you’re shopping and see an item that is originally priced at $20 but is now being sold for $13, you can quickly calculate that the discounted price represents 65% of the original price using the formula and process outlined above.
