Do you need to round numbers to one decimal place? Maybe you’re doing some math homework, or maybe you’re working on a budget and need to be precise. Whatever the reason, it’s easy to do! In this blog post, we will show you a simple trick to how to round to one decimal place quickly and easily. Let’s get started!

Look at the digit in the tenth position to round a number to one decimal place. This is the number following the decimal point. You round down if the number is between 0 and four. If the number is between 5 and 9, round up. Let’s put it to the test with some examples!

Example One:

You want to round 20.456 to one decimal place. The fourth digit after the decimal point is a five, so we round up. This gives us 20.46.

Example Two:

You want to round 12.893 to one decimal place. The third digit after the decimal point is an eight, so we round up. This gives us 12.90.

## How to check your work:

To check your work, you can use a calculator or a piece of paper and a pencil. Write down the number that you want to round and put a line after the tenth digit. This will help you keep track of where the decimal point is.

Then, round up or down based on the number in the tenth position. You can also use this method to round numbers to other decimal places, like two or three!

## Common mistakes:

One common mistake is to round the number based on the digit in the ones place. This will give you the wrong answer! Remember to always look at the tenths place when rounding numbers to one decimal place.

Another common mistake is to round a number up or down without considering what the number in the tenth position is. For example, if you want to round 23.45 down, you might mistakenly write 23 instead of 23.40. Be careful and double check your work to avoid making this mistake!

### How to avoid making mistakes:

The greatest approach to minimise rounding errors is to practise, practise, practise! The more you do it, the simpler it will become. You may also try checking your work using a calculator or a piece of paper and a pencil.

This will assist you in detecting any errors.
