**How to order decimal numbers to (2 d.p)**

**Look** at the direction that you need to order in, ascending or descending.

**Place in ascending order 1.28 1.39 1.12 1.21 1.20 **

**If** ascending look for the smallest number first, by comparing the first digit of each number.

So the smallest number is** 18
**

** -**If you have more than one number starting with the same digit, you then need to compare the next set of digits in those numbers ie- **15 12 **would become **12 15**

So you now have **18 **followed by **19, **repeat the process until all the numbers are used.

So the ascending order is** 18 19 20 21 22**

**If** descending look for the largest number first, by comparing the first digit of each number.

So the largest number is** 22
**

** -**If you have more than one number starting with the same digit, you then need to compare the next set of digits in those numbers ie- **15 12 **would stay as **15 12 **as 5 is larger than 2 in descending order.

So you now have **22 **followed by **21, **repeat this process until all the numbers are used.

So the descending order is **22 21 20 19 18**
