# Rounding Decimal Numbers Part 1

Recall the place value chart. The number 12.35 can be written in the place value chart as follows:

Ones |
Tens |
. |
Tenths |
Hundredths |

1 | 2 | . |
3 | 5 |

Steps for rounding decimals:

To round the decimal number to a given place, locate the rounding digit (which is the digit at the place you are rounding to). Then, check the digit immediately to its right.

- If this digit is 5 or more, then add 1 to the rounding digit (this is called rounding up) and remove all the digits to its right.

- If this digit is less than 5, then keep the rounding digit the same (this is called rounding down) and remove all the digits to its right.

**For example: **To round the number 70.17 to the nearest tenths, look at its hundredths place digit.

It is 7, which is greater than 5. So, we round up.

70.17 → 70.2

So, 70.17 rounded to the nearest tenth is 70.2.
