Rounding is an important math skill that is used in many different situations. It can be used to simplify long numbers, or to estimate answers to math problems. When rounding to the nearest tenth, you are rounding a number to the nearest tenths place. For example, 8.9 rounded to the nearest tenth would be 9.0.

## How to Round 8.9 to the Nearest Tenth

To round a number to the nearest tenth, you must first look at the digit to the right of the tenths place. If that digit is less than 5, you round down, and if it is 5 or greater, you round up. In this case, 8.9 has a 9 in the tenths place, so we must look at the digit to the right of the 9. Since there is no digit to the right, we can assume it is 0. Since 0 is less than 5, we round down. So 8.9 rounded to the nearest tenth is 9.0.

## Examples of Rounding to the Nearest Tenth

Here are a few more examples of how to round to the nearest tenth: 8.4 rounded to the nearest tenth is 8.4, 8.5 rounded to the nearest tenth is 8.5, 8.6 rounded to the nearest tenth is 8.6, and 8.7 rounded to the nearest tenth is 8.7. As you can see, any number with a 0, 1, 2, 3, or 4 in the tenths place is rounded down, while any number with a 5, 6, 7, 8, or 9 in the tenths place is rounded up.

## Why Is Rounding to the Nearest Tenth Important?

Rounding to the nearest tenth is important because it can help simplify long numbers or estimate answers to math problems. In addition, rounding to the nearest tenth can help us make decisions when dealing with money. For example, if a store is selling an item that costs $8.99, it is often easier to round up to $9.00 than it is to pay the exact amount, which is why most stores round up or down when calculating prices.

Rounding to the nearest tenth is a useful math skill that can help simplify long numbers or estimate answers to math problems. It is important to remember that any number with a 0, 1, 2, 3, or 4 in the tenths place is rounded down, while any number with a 5, 6, 7, 8, or 9 in the tenths place is rounded up. By understanding how to round to the nearest tenth, you can make more informed decisions and save time when solving math problems.
