Same 4 2 3 2 6

Same 4 2 4 1 8

Different
3 < 4
Hence, 42326 < 42418.
Example 2: Compare 7,83,511 and 7,83,495.

Solution: Both the numbers have 6-digits. So, we start comparing the digits from the left-
most end.

7 8 3 5 1 1 7 8 3 4 9 5 L TTh Th H T O
Same 7 8 3 5 1 1

Same 7 8 3 4 9 5

Same 5 > 4

Different
Hence, 783511 > 783495.

Example 3: Which of the following is the greatest?

25,17,01,294; 15,27,01,294; 25,17,40,294
Solution: Line up the numbers by their place TC C TL L TTh Th H T O
values and start comparing from the 2 5 1 7 0 1 2 9 4

left most digit. 1 < 2 1 5 2 7 0 1 2 9 4
1 < 2 2 5 1 7 4 0 2 9 4

So, 152701294 is the smallest number. 0 < 4

Now, we have to compare between 251701294 and 251740294.
Now, cross out the equal digits at corresponding places from both number. We
find that at ten thousands place
0 < 4

So, 152701294 < 251701294 < 251740294
Hence, the greatest number is 251740294.

Ascending Order or Descending Order
More than two numbers can be compared in the same manner and can be arranged in ascending
or descending order.

Ascending Order: It means, ordering numbers from the smallest to the greatest.
Descending Order: It means, ordering numbers from the greatest to the smallest.
