To calculate a percentage, follow these steps:
- Determine the Value: Identify the value or quantity you want to calculate the percentage of. Let's call this value "A".
- Determine the Total or Reference Value: Determine the total or reference value to which you want to calculate the percentage. Let's call this value "B".
- Divide Value A by Value B: Divide the value you want to calculate the percentage of (Value A) by the total or reference value (Value B).
- Multiply by 100: Multiply the result from step 3 by 100 to convert it to a percentage.
The formula can be summarized as:
Percentage = (Value A / Value B) * 100
Here are a few examples to illustrate how to calculate percentages:
Example 1:
You scored 85 marks out of 100 on a test. What is your percentage score?
Percentage = (85 / 100) * 100 = 85%
Example 2:
You bought a product that was originally priced at $50 but was discounted to $40. What is the percentage discount?
Percentage = [(Original Price - Discounted Price) / Original Price] * 100
Percentage = [(50 - 40) / 50] * 100 = 20%
Example 3:
You want to calculate what percentage 25 is of 80.
Percentage = (25 / 80) * 100 = 31.25%
These are the basic steps to calculate a percentage. Remember to adjust the formula based on the specific context and values you are working with.
