To find 25% of 80, you can use the formula for percentage calculation, which is:

\[

\text{Percentage} = \left(\frac{\text{Percent}}{100}\right) \times \text{Whole}

\]

In this case, the percent is 25 and the whole is 80. Plugging in these values gives:

\[

25\% \text{ of } 80 = \left(\frac{25}{100}\right) \times 80

\]

First, simplify \(\frac{25}{100}\):

\[

\frac{25}{100} = 0.25

\]

Now, multiply 0.25 by 80:

\[

0.25 \times 80 = 20

\]

Therefore, 25% of 80 is 20, confirming that the correct answer is indeed 20. This calculation demonstrates how to effectively convert a percentage into a decimal and then perform the multiplication to arrive at the desired portion of the whole number.
