Question: 1 / 400

What is 15% of 80?

8

10

12

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 \
