Comparison Rules

Rule 1: If a number has more digits than another, it is the greater of the two.

Example: Compare 3457 and 621.

Solution: Here, the number 3457 has 4 digits and the number 216 has 3 digits.

Since, 4 > 3

So, 3457 > 621

Rule 2: If two numbers have the same number of digits, we compare them by their extreme leftmost digits. The number with the greater digit is greater.

Example: Compare 6568 and 4265.

Solution : Here, both the numbers have 4 digits. So, observe the digits at the thousands place.

Rule 3:

 If two numbers have the same number of digits and their extreme leftmost digits are also same, we compare them by their next digits to the right and so on.

Example: Compare 3457 and 621. Example: Compare 6568 and 4265. Example: Compare 6268 and 6165.

Solution : Here, both the numbers have 4 digits. Also, the extreme leftmost digits are the same. So, we compare the digits to the right of 5.

So, 6268 > 6165
