In this comprehensive guide, we will break down the concept of percentages, show you step-by-step how to calculate them, and provide real-life examples to help you understand how percentages work. By the end of this article, you’ll be a pro at calculating percentages and solving questions like “20 is what percent of 300?”
Understanding Percentages
Percentages are one way of expressing a proportion or a fraction of a whole, with the whole being represented by 100%. It is a way of comparing numbers to 100 and is commonly used in everyday life, from calculating discounts at the store to understanding statistics and financial data.
When we say “20 is what percent of 300,” we are essentially trying to find out what portion or fraction of 300 is represented by 20. In other words, we want to express 20 as a percentage of 300.
Calculating Percentages
Calculating percentages involves a simple formula:
Percentage = (Part/Whole) x 100
Where:
- Percentage is the value we are trying to find
- Part is the value we have (in this case, 20)
- Whole is the total value (in this case, 300)
Calculating “20 is What Percent of 300”
Now that we understand the formula for calculating percentages, let’s apply it to the question at hand: “20 is what percent of 300?”
Using the formula, we can calculate:
Percentage = (20/300) x 100
Percentage = 0.0667 x 100
Percentage = 6.67%
So, 20 is 6.67% of 300.
Real-life Examples of Percentages
Understanding percentages becomes easier when we see how they are used in real-life scenarios. Here are a few examples:
- If a store is offering a 20% discount on a $300 item, the discount would be $60 (20% of 300).
- If an investment grows by 10% annually, a $300 investment would grow by $30 in a year (10% of 300).
- If you scored 85% on a test with a total of 300 marks, you would have scored 255 marks (85% of 300).
Understanding Fractional Equivalents
Another way to understand percentages is to express them as a fraction. In our example, we found that 20 is 6.67% of 300. This can also be expressed as a fraction:
6.67% = 6.67/100 = 0.0667
So, 6.67% as a fraction is 0.0667. This means that out of the whole (300), 20 represents 0.0667 or 6.67%.
