Worksheet Overview

Numbers with one decimal place have one digit after the decimal point.

To round one of these numbers to the nearest whole number, think of a number line.


Remember that halfway numbers such as 7.5 or 8.5 or 14.5 always round UP.


Numbers ending in 1, 2, 3 and 4 round DOWN.

Numbers above this, such as 5, 6, 7, 8 and 9 round UP.




Example 1

Round 12.3 to the nearest whole number.



12.3 is between 12 and 13 and is closer to 12.

12.3 rounds down to 12.



Example 2

Round 10.8 to the nearest whole number.



10.8 is between 10 and 11 and is closer to 11.

10.8 rounds up to 11.



Example 3

Round 16.5 to the nearest whole number.



16.5 is halfway between 16 and 17 and so we round up.

16.5 rounds up to 17.
