1. Set up a table with the decimal point in the same place for each number.

2. Put in each number.

3. Fill in the empty squares with zeros

4. Compare using the the first column on the left

5. ​If the digits are equal move to the next column to the right until one number wins.

Steps to take in ordering decimals​

NB:

• If you want ​ascending order you always pick the smallest first.​

• If you want ​descending order you always pick the largest first.

Following the steps

​1.506, 1.56, 0.8

​1	​	​5	​6	​0
​0	​	​8	​0	​0

​Comparing with my left column; Two of them are "1"s and the other is a "0". Ascending order needs smallest first, and so "0" is the winner:

Answer so far: 0.8

Following the steps

​1.506, 1.56, 0.8

Step

​

​Ones	​Decimal Point	​Tenths	​Hundredths	​Thousandths
​1	​	​5	​0	​6
​1	​	​5	​6	​0
​0	​	​8	​0	​0

​Comparing with my tenths column; now there are two numbers with the same "Tenths" value of 5, so move along to the "Hundredths" for the tie-breaker

Following the steps

​1.506, 1.56, 0.8

Step

6

​

​Ones	​Decimal Point	​Tenths	​Hundredths	​Thousandths
​1	​	​5	​0	​6
​1	​	​5	​6	​0
​0	​	​8	​0	​0

​Comparing with my hundredths column; one of those has a 6 in the hundredths, and the other has a 0, so 0 wins (remember we are looking for the smallest each time). In other words 1.506 is less than 1.56: Answer so far: 0.8, 1.506

Following the steps

​1.506, 1.56, 0.8

​

​Ones	​Decimal Point	​Tenths	​Hundredths	​Thousandths
​1	​	​5	​0	​6
​1	​	​5	​6	​0
​0	​	​8	​0	​0

​Only one number left, it must be the largest: Answer: 0.8, 1.506, 1.56
