Sometimes in real life, we can’t use decimals. For example, the number of people you are inviting to a party can’t be a decimal number. You can’t have 8.7 people, but you can have 8 or 9 people. Rounding to the nearest whole number is how we deal with problems like this. The table below shows the rules for whether you round up (from 4.56 to 5) or down (from 4.46 to 4).

Tenths Place | How to round to nearest whole number or integer | Example |

0, 1, 2, 3, 4 | Keep the number in the one's place | 17.4 Rounds to 17 -3.4 rounds to -3 |

5, 6, 7, 8, 9 | Increase the number in the one's place by 1 | 17.5 Rounds to 18 -1.6 Rounds to -2 |
