By applying the formula:

Percentage = (Number * Percentage) / 100

In our case:

Percentage = (80 * 25) / 100
           = 2000 / 100
           = 20

Therefore, finding that 25% of 80 equals 20.

Example: What percent is 15 out of 50?

Now let’s move on to another scenario where we need to determine what percentage a particular number represents within another number. Consider the question: What percentage is 15 out of 50 in terms of percentage points?

To find the answer, divide the given number (15) by the total value (50), and then multiply by 100 to obtain the percentage representation.

Using the formula:

Percentage = (Number / Total) * 100

In our case:

Percentage = (15 /50) *100
           =0.3 *100 

Hence, we conclude that when considering a quantity of only fifteen within fifty, it represents thirty percentage points.

These examples showcase practical applications where percentage calculations come into play in everyday scenarios. Understanding how to find percentages allows you to make informed decisions and perform calculations with ease.
