What is the formula for determining percentage?
The formula for determining a percentage is:
Percentage = (Part / Whole) x 100
Here's what each part of the formula represents:
Percentage: This is the portion of the whole you want to express as a percentage.
Part: This is the specific value or quantity you want to find the percentage of within the whole.
Whole: This is the total or the whole amount that the part is a portion of.
To calculate a percentage, simply plug in the values for "Part" and "Whole" into the formula, and then multiply the result by 100 to express it as a percentage.
The formula for determining percentage is:
Percentage = (Part / Whole) * 100
Where:
- Part is the value you want to find the percentage of.
- Whole is the total value.
- Percentage is the result, expressed as a percentage.
For example, if you want to find the percentage of 20 out of 100, you would use the following formula:
Percentage = (20 / 100) * 100 = 20%
This means that 20 is 20% of 100.
Here is another example:
If you have a class of 30 students and 24 of them pass the exam, you can use the following formula to find the percentage of students who passed:
Percentage = (24 / 30) * 100 = 80%
This means that 80% of the students passed the exam.
You can also use the percentage formula to calculate percentages of increases and decreases. For example, if you bought a product for $100 and it is now on sale for $80, you can use the following formula to find the percentage decrease in price:
Percentage decrease = ((100 - 80) / 100) * 100 = 20%
This means that the price of the product has decreased by 20%.
Percentages can be used in many different areas of life, such as business, finance, and education. By understanding the percentage formula, you can calculate percentages with confidence and make informed decisions.
