## The Basics of Percentages

Before we dive into the calculation of 80 percent of 10, let’s first review the basics of percentages. A percentage is a way of expressing a part of a whole as a fraction of 100. For example, 50 percent means half of the whole, or 50 out of 100.

Percentages are commonly used in everyday life, such as in sales discounts, interest rates, and grades. Knowing how to calculate percentages is a useful skill that can help you make informed decisions.

## Calculating 80 Percent of 10

Now, let’s get back to the question at hand: what is 80 percent of 10? To calculate this, we need to multiply 10 by 80 percent as a decimal.

First, we convert 80 percent to a decimal by dividing it by 100:

80 percent ÷ 100 = 0.8

Next, we multiply 10 by 0.8:

10 x 0.8 = 8

Therefore, 80 percent of 10 is 8.

### Why Knowing Percentages is Important

As mentioned earlier, knowing how to calculate percentages can be useful in many situations. For example, if you are shopping and see a discount of 25 percent off a $20 item, you can quickly calculate the sale price:

25 percent ÷ 100 = 0.25

$20 x 0.25 = $5

The sale price would be $20 – $5 = $15.

Calculating percentages can also be helpful in budgeting, such as determining how much of your income should be allocated to different expenses.

### Common Percentage Calculations

Here are some common percentage calculations:

- 50 percent of 100 = 50
- 10 percent of 200 = 20
- 75 percent of 80 = 60
- 20 percent off $50 = $10
- 30 percent increase from 70 = 91

## Conclusion

In conclusion, calculating percentages is a basic but important skill that can be useful in many situations. To calculate 80 percent of 10, we multiply 10 by 80 percent as a decimal, which gives us 8. So, if you ever come across this question, you now know the answer!
