In this article, we will explore the concept of finding 30% of 20 and explain the steps involved in solving such a problem.
Understanding Percentages
What exactly is a percentage?
A percentage is a way of expressing a fraction or a proportion out of 100. It is denoted by the symbol %. For instance, if we say 30%, it means 30 out of every 100. So, when we need to find a certain percentage of a number, we are essentially calculating a fraction or a portion of that number.
Calculating 30% of 20
What does it mean to find 30% of 20?
To calculate 30% of 20, we need to determine what fraction or portion of 20 represents 30%. In other words, we want to find 30% of the whole quantity of 20.
Step 1: Convert the Percentage to a Decimal
The first step is to convert the given percentage (30%) into a decimal. To do this, divide the percentage value by 100. In our case, since we have 30%, we divide 30 by 100:
30 ÷ 100 = 0.3
Step 2: Multiply the Decimal by the Given Number
Now that we have converted 30% to a decimal (0.3), we multiply this decimal by the given number (20) to find 30% of 20:
0.3 × 20 = 6
The Solution
Therefore, 30% of 20 is equal to 6. In other words, if we take 30% of the quantity 20, the result will be 6.
Real-Life Examples
How can this concept be applied in real-life situations?
Understanding how to calculate percentages can be useful in various scenarios. For instance:
Example 1: Discounts
If an item is on sale with a 30% discount, and its original price is $20, you can find the discounted price by calculating 30% of $20 using the steps we discussed earlier. In this case:
30% of $20 = 0.3 × $20 = $6
The discounted price would be $20 - $6 = $14.
Example 2: Taxes
In some regions, sales tax may be added to the total cost of goods or services. If the tax rate is 30% and the total bill amounts to $20, you can find the tax amount by calculating 30% of $20:
30% of $20 = 0.3 × $20 = $6
The tax amount would be $6.
In Conclusion
Calculating percentages is a valuable skill that allows us to understand proportions and make sense of various real-life scenarios. By following the steps outlined in this article, finding a percentage of a given number becomes a straightforward process. So, the next time you encounter a problem like What is 30% of 20?, you can confidently apply the steps we discussed to arrive at the correct answer.
