#### Worksheet Overview

Numbers with 2 decimal places have 2 digits after the decimal point.

To round one of these numbers to the nearest 1 decimal place number think of a number line.

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

Numbers above this, those ending in 5, 6, 7, 8 and 9 round UP.

Remember that halfway numbers, such as 7.50 round UP.

Here 7.35 is between 7.3 and 7.4, but rounds up to 7.4 to one decimal place.

Example 1

Round 12.63 to one decimal place.

12.63 is between 12.6 and 12.7, but is closer to 12.6.

12.63 rounds down to 12.6.

Example 2

Round 10.38 to one decimal place.

10.38 is between 10.3 and 10.4, but is closer to 10.4.

10.38 rounds up to 10.4.

Example 3

Round 16.65 to one decimal place.

16.65 is halfway between 16.6 and 16.7 and so we round up.

16.65 rounds up to 16.7.
