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

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

Numbers whose first decimal places is **0**, **1**, **2**, **3**, **4** round **DOWN**.

Numbers whose first decimal places is **5**, **6**, **7**, **8** and **9** round **UP**.

Remember that halfway numbers, such as 7.50 round **UP**.

Here 7.35 has a 3 in its first decimal place so rounds **DOWN** to 7.

And 7.58 has a 5 in its first decimal place so rounds **UP** to 8.
