The Basics
When it comes to math, some calculations are easier than others. One question that you may have come across is “what is 10 of 800?” The answer is simple: 80. But, let’s dive a little deeper into what that means.
When we ask “what is 10 of 800,” we are essentially asking what 10% of 800 is. In other words, we want to know what number we get when we take 10% of 800.
What is a Percentage?
Before we delve into percentages, let’s first define what they are. A percentage is a way of expressing a number as a fraction of 100. It is denoted using the symbol “%.”
For example, if you have 10 apples and you want to express this as a percentage of 20 apples, you would say that you have 50% of the apples.
Calculating Percentages
Now that we know what percentages are, let’s learn how to calculate them. To calculate a percentage, we need to divide the number we want to find the percentage of by the total number, and then multiply the result by 100.
So, to find 10% of 800, we would first divide 800 by 100, which gives us 8. Then, we would multiply 8 by 10, which gives us 80.
Why is Knowing Percentages Important?
Percentages are used in many different fields, such as finance, science, and statistics. They are also used in everyday life, such as calculating tips, discounts, and taxes.
Knowing how to calculate percentages can help you make informed decisions about your finances, such as determining how much interest you will be charged on a loan or how much money you will save by using a coupon.
Real-Life Examples
Let’s look at some real-life examples of how percentages are used:
1. If you have a $100 bill and you want to leave a 20% tip at a restaurant, you would leave $20.
2. If a store is offering a 25% discount on a $50 item, you would pay $37.50.
3. If you have a 6% interest rate on a $10,000 loan, you will pay $600 in interest over the course of a year.
Conclusion
In conclusion, knowing how to calculate percentages is an important skill that can be used in many different fields. When someone asks “what is 10 of 800,” they are essentially asking what 10% of 800 is, which is 80. By understanding percentages, you can make informed decisions about your finances and everyday life.
