## Comparing Decimal Fractions – Definition

In a comparison of decimal fractions, we know that a decimal number has two parts i.e whole number part and decimal part. Comparison of decimals are notated as >, =, and <

- > used as a sign to indicate a greater number.
- < used as a sign to indicate a lesser number.
- = used as a sign to indicate that both are equal numbers.

### How to Compare Decimal Fractions?

Go through the simple steps listed below for Comparing Decimal Fractions. They are in the below fashion

- First, check the whole number part of the given decimal numbers, assign the sign accordingly.
- If both given decimal numbers have the same whole number part, then compare the digits in the decimal part.
- If the tens digit in decimal place is also the same, then go for the hundreds digit and compare the numbers.
- If the digits in hundreds place are also the same, then compare the digits in further place and assign the sign.

**Note:** To make comparison easy, first convert the given decimals to like decimals and compare the numbers.

### Comparing Decimals Examples

**Example 1:**

Compare 0.5 and 1.8?

**Solution:**

Given numbers are 0.5 and 1.8

Compare the whole number part of given decimal numbers that is

0 < 1

So, Now 1.8 is greater than 0.5.

**Example 2.**

Compare 0.4 and 0.8

**Solution:**

Given numbers are 0.4 and 0.8

Compare the whole number part of given decimal numbers that is

0 = 0

Now compare the digits in decimal part, a digit in tens place that is

4 < 8

So, Now 0.8 is greater than 0.4.

**Example 3.**

Compare 1.53 and 1.59

**Solution:**

Given numbers are 1.53 and 1.59

Compare the whole number part of given decimal numbers that is

1 = 1

Now compare the digits in decimal part, a digit in tens place that is

5 = 5

If the digit in tens place is equal then compare the next digit in hundreds place that is

3 < 9

So, Now 1.59 is greater than 1.53.

**Example 4.**

Compare 19.537 and 19.532?

**Solution:**

Given numbers are 19.537 and 19.532

Compare the whole number part of given decimal numbers that is

19 = 19

Now compare the digits in decimal part, a digit in tens place that is

5 = 5

If the digit in tens place is equal then compare the next digit in hundreds place that is

3 = 3

If the digit in hundreds place is equal then compare the next digit in thousands place that is

7 > 2

So, Now 19.537 is greater than 19.532.

**Example 5.**

Find which is greater in 209.116 and 209.118?

**Solution:**

Given numbers are 209.116 and 209.118

Compare the whole number part of given decimal numbers that is

209 = 209

Now compare the digits in decimal part, a digit in tens place that is

1 = 1

If the digit in tens place is equal then compare the next digit in hundreds place that is

1 = 1

If the digit in hundreds place is equal then compare the next digit in thousands place that is

8 > 6

So, Now 209.118 is greater than 209.116.

**Example 6.**

Find which is greater in 178.676 and 178.6

**Solution:**

Given numbers are 178.676 and 178.6

Compare the whole number part of given decimal numbers that is

178 = 178

Now compare the digits in decimal part, a digit in tens place that is

6 = 6

Now as the given numbers are not having equal decimal places so convert them into like decimals by adding zeros

we get 178.676 and 178.600

If the digit in tens place is equal then compare the next digit in hundreds place that is

7 > 0

So, Now 178.676 is greater than 178.600.

**Example 7.**

Write the following in ascending order

2.8, 2,801, 2.87, 2.81

**Solution:**

Given numbers

2.8, 2,801, 2.87, 2.81

To make comparison easy convert the given numbers into like decimals

Among the given numbers, the highest number of decimal places is 3, so add zeros accordingly

we get,

2.800, 2.801, 2.870, 2.810

By following steps rearrange them into ascending order

Now,

2.800 < 2.801 < 2.810 < 2.870.

**Example 8.**

Write the following in descending order

19.8, 19.01, 19.567, 19.2217

**Solution:**

Given numbers

19.8, 19.01, 19.567, 19.2217

To make comparison easy convert the given numbers into like decimals

Among the given numbers, the highest number of decimal places is 4, so add zeros accordingly

we get,

19.8000, 19.0100, 19.5670, 19.2217

By following steps rearrange them into descending order

Now,

19.8000 > 19.5670 > 19.2217 > 19.0100.
