What is 15% of 80?

To find 15% of 80, you can use the formula for calculating a percentage, which is:

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

In this case, the percent is 15, and the whole is 80. Plugging in these values gives:

[ 15% \text{ of } 80 = \left( \frac{15}{100} \right) \times 80 ]

To simplify this calculation, first convert 15% to its decimal form by dividing 15 by 100:

[ 15% = 0.15 ]

Now perform the multiplication:

[ 0.15 \times 80 = 12 ]

To visualize this, you can break it down further. First, calculate 10% of 80, which is 8, and then find 5% of 80. Since 5% is half of 10%, you can take half of 8 to get 4. Finally, you add 10% (8) and 5% (4) together:

[ 8 + 4 = 12 \
