To find 20 percent of 100, you can use the formula:
Percentage = (Part / Whole) * 100
In this case, we want to find the "part" when we know the "percentage" (20%) and the "whole" (100). So, we rearrange the formula to find the part:
Part = (Percentage / 100) * Whole
Calculating 20 Percent of 100
Using the formula, we get:
Part = (20 / 100) * 100 = 20
Subtracting from the Whole
Now that we know 20 percent of 100 is 20, we can subtract that from the original number:
100 - 20 = 80
Therefore, 100 minus 20 percent is 80.
Real-World Applications
This type of calculation is helpful in various scenarios, such as:
- Discounts: Calculating the final price of an item after a discount.
- Sales Tax: Determining the price before tax is added.
- Budgeting: Managing expenses and savings.
Alternative Calculation Method
Instead of calculating 20% and then subtracting, you can directly calculate 80% of 100, since subtracting 20% leaves you with 80% of the original value.
80% of 100 = (80 / 100) * 100 = 80
This method gives you the answer in one step.
