Answer for screen readers
The rounded number is 2.5.
Steps to Solve
- Identify the tenths place
In the number 2.5, the tenths place is the first digit to the right of the decimal point. Here, the tenths digit is 5.
- Examine the next digit
Look at the next digit to the right of the tenths place to understand if you need to round up or down. In 2.5, there are no digits after the 5, which can be considered as 0.
- Determine how to round
Since there is no digit after the 5 (or it can be viewed as 0), we do not round up. If the digit were 5 or greater, we would round up the tenths digit to 6. However, since it is 0, we keep it as 5.
- Write the rounded number
The final rounded number is 2.5 since we only rounded it to the nearest tenth.
The rounded number is 2.5.
More Information

Tips
- Forgetting to check the digit after the tenths place can lead to incorrect rounding. Always remember to check the next digit to determine if you round up or down.
