Ordering decimals means putting them in order from the smallest to the largest (ascending) or from the largest to the smallest (descending). It helps you quickly see which numbers are bigger, smaller, or equal. This process, also called comparing and ordering decimal, makes it easier to understand how decimal numbers relate to each other. Let’s try the example below to see how it works in practice.
 

Question: Compare which among the following numbers is smaller and larger: 0.03, 0.30, 0.13, 0.311, 0.131. 

Solution: 

Step 1: First, we need to arrange the numbers in ascending to descending order. For that let’s draw a table with ones, tenths, hundredths, and thousandths.

Ones

Decimal Point

Tenths

Hundredths

Thousandths

0

-

0

3 -

0

- 3 0 -

0

- 1 3 -

0

- 3 1 1

0

- 1 3 1


Step 2: Now, check the tenths decimal values. 

Here, the tenth place values are 0, 1, 1, 3, 3.

0 < 1, 1, 3, 3

So, we got the smallest number from the group. That is, 0.03.

Step 3: Next, move to the next biggest number the tenths place values are 1, 1, 3, 3. Which is 1. 
 

Since there are two numbers with 1, we have to move to the next decimal number to know which one is bigger. 
 

Here, the hundredths place digits are 3 for both numbers. So, we should move to the next decimal number. 
 

Then the next place value is thousandths, which are 0 and 1. 

0 < 1

So we get that 0.13 < 0.131. 

Now, we have got 0.03, 0.13, 0.131.

Step 4: Move to the next highest value among 3, 3.

Both of them are equal, so we have to again check the hundredths place value.

The hundredths place values are 0 and 3. So, 0 < 3.

So we get that 0.30 < 0.311. 

Step 5: Arrange them in ascending order. 

 0.03, 0.13, 0.131, 0.30, 0.311

Step 6: Analyze the smallest number and the largest number in the results. Thus, 

 0.03 is the smaller number  

 0.311 is the larger number
