How to calculate percentage?
The formula to find a percentage is:
Percentage = (Part / Whole) * 100
Here, "Part" represents the quantity you want to find the percentage of, and "Whole" represents the total or the whole amount.
Let's consider an example to illustrate how to find a percentage:
Example 1: Sarah scored 80 out of 100 on her math test. What is her percentage score?
In this example, Sarah's score of 80 is the part, and the total possible score of 100 is the whole. Using the formula, we can calculate the percentage as follows:
Percentage = (80 / 100) * 100 = 80%
Therefore, Sarah's percentage score on the math test is 80%.
Example 2: A store offers a 20% discount on a $50 item. What is the discounted price?
In this example, the discount of 20% represents the part, and the original price of $50 represents the whole. To find the discounted price, we can use the formula:
Discounted Price = Original Price - (Original Price * Percentage)
Percentage = 20% = 0.20 (in decimal form)
Discounted Price = $50 - ($50 * 0.20) = $50 - $10 = $40
Therefore, the discounted price of the item is $40.
Example 3: In a survey, out of 200 people, 150 said they prefer coffee. What percentage of people prefer coffee?
In this example, the number of people who prefer coffee (150) represents the part, and the total number of people surveyed (200) represents the whole. Using the formula, we can calculate the percentage as follows:
Percentage = (150 / 200) * 100 = 75%
Therefore, 75% of the people surveyed prefer coffee.
In summary, a percentage is a way of expressing a fraction or proportion as a fraction of 100. To find a percentage, you need to divide the part by the whole and then multiply by 100. This formula allows you to compare and quantify proportions, making percentages a valuable tool in various calculations and real-life situations.
