Introduction
In mathematics, it is common to encounter problems that involve finding a certain percentage of a given number. One such problem is determining what 20% of 90 is. In this article, we will explore the process of calculating this percentage and provide a step-by-step explanation.
Understanding Percentages
Before diving into the calculation itself, it is important to understand the concept of percentages. A percentage is a way of expressing a fraction or ratio out of 100. It allows us to compare different quantities and make meaningful comparisons.
What is a Percentage?
A percentage represents a fraction of a whole, where the whole is always equivalent to 100%. For example, 50% is the same as 50 out of 100, or 1/2. Similarly, 25% is equivalent to 25 out of 100, or 1/4. Percentages are widely used in various fields, including finance, statistics, and everyday calculations.
Calculating 20% of 90
To find 20% of 90, we need to multiply 90 by the decimal equivalent of 20%. To convert a percentage to a decimal, we divide it by 100. Therefore, 20% becomes 0.20 as a decimal.
Multiplying 90 by 0.20
Next, we multiply 90 by 0.20 to determine the result. Multiplying these two numbers gives us 18, which represents 20% of 90. In other words, 18 is what you get when you take 20% of 90.
Interpreting the Result
The answer, 18, signifies that 20% of 90 is equal to 18. This means that if you were to divide 90 into five equal parts, each part would be 18. Alternatively, you can think of it as taking away 20% of 90, leaving you with the remaining 80%.
Using Percentages in Real Life
Percentages are not only used in mathematical calculations but also in real-life scenarios. For example, if you receive a discount of 20% on an item priced at $90, you would save $18. Understanding percentages allows you to make informed decisions about sales, discounts, and other financial matters.
Finding Other Percentages
The process of finding a percentage is similar regardless of the numbers involved. By converting the percentage to a decimal and multiplying it by the given number, you can calculate any percentage easily.
Examples:
What is 30% of 120? To find this, convert 30% to 0.30 and multiply it by 120. The result is 36, so 30% of 120 is equal to 36.
Similarly, what is 15% of 200? Converting 15% to 0.15 and multiplying it by 200 gives us 30. Therefore, 15% of 200 is 30.
Conclusion
Calculating percentages is a fundamental skill in mathematics and everyday life. By understanding the concept of percentages and employing the method explained in this article, you can easily find any percentage of a given number. In the case of 20% of 90, the answer is 18. So, the next time you encounter a percentage problem, you can approach it confidently and solve it accurately.
Introduction: Understanding the Concept
Percentages play a crucial role in various aspects of our daily lives, from calculating discounts during shopping to determining interest rates on loans. Understanding how to calculate percentages is essential for making informed decisions and solving real-life problems. In this article, we will break down the concept of finding 20% of 90 and explore different methods to calculate it.
Definition: Breaking Down the Calculation
When we say 20% of 90, we are referring to finding the value that represents 20% of the total value of 90. This means we need to determine what 20% of 90 is and express it in a meaningful way.
Calculation Method: Breaking it Down Step by Step
To calculate 20% of 90, we can follow a straightforward method:
- Step 1: Convert the percentage to a decimal form.
- Step 2: Multiply the decimal form with the given value.
- Step 3: Obtain the result, which represents 20% of 90.
Percentage Calculation: Simplifying the Relationship
Before proceeding with the calculation, let's understand the relationship between percentages and their decimal equivalents. Percentages are essentially fractions out of 100, where 100% represents the whole. For example, 50% is equivalent to 50/100 or 0.5 as a decimal.
Equivalent Fraction: Expressing 20% of 90 in Fraction Form
To find 20% of 90 in fraction form, we can convert 20% to its equivalent fraction. Since 20% is 20 out of 100, we can express it as 20/100. Simplifying this fraction gives us 1/5. Therefore, 20% of 90 is equal to 1/5 of 90.
Decimal Form: Converting 20% to Decimal
Converting a percentage to its decimal form is necessary for our calculation. To convert 20% to decimal, we divide it by 100. Thus, 20% becomes 0.2 in decimal form.
Summarizing the Result: Finding 20% of 90
Now that we have converted 20% to its decimal form, we can proceed with the calculation. Multiplying 0.2 by 90, we find that 20% of 90 is equal to 18. Therefore, if we want to find 20% of 90, the result is 18.
Practical Application: Applying the Concept in Real-life Scenarios
The ability to calculate percentages is incredibly useful in real-life situations. For instance, when shopping during a sale, knowing how to find 20% of the original price allows us to determine the discounted amount. Similarly, when calculating taxes or tips, understanding percentages enables us to make accurate calculations and avoid overpaying.
Comparing with Other Percentages: Understanding the Impact of Different Percentages
By comparing different percentages, we can understand their impact on a given value. For example, let's compare 20% and 50% of 90. Using the same method as before, we find that 50% of 90 is equal to 45. Comparing this with the previous result of 18, we see that 50% has a greater impact than 20% on the total value of 90.
Final Thoughts: Reviewing the Importance of Understanding Percentages
