What are Three-Digit Numbers?
Three-digit numbers have only three digits. In three-digit numbers, the numbers are placed at one’s, ten’s, and hundred’s place. In the right of the number the last digit is one’s place, then the second digit is ten’s place and to the left of it, there is a hundred’s place. The digits have their face value in a given number. Three-digit numbers are from 100 to 999.
For example, in 635 the place value of 6 is 600, 3 is 30, and 5 is 5. In other words, we can write this as six hundred thirty-five.
How to Compare Three-Digit Numbers?
Know the procedure on how to compare 3 digit numbers by going through the below-listed steps. They are along the lines
(i) The numbers which have less than three digits are always smaller than the numbers having three digits as:
128 > 73 , 120 > 7 or 7 < 120 , 58 < 158
175 > 65 , 529 > 59 , 703 > 8 , etc.
(ii) If both the numbers have the same number (three) of digits, then the digits of the hundred-place and tens place are compared.
a) If the third digit from the right (Hundred-place digit) of a number is greater than the third digit from the right (Hundred-place digit) of the other number then the number having the greater is the greater one.
855>713, 984>981, 100>9,100>99.
b) If the numbers have the same third digit from the right, then the digits at ten’s place are compared and follow the rules of comparison of two-digit numbers.
967 > 929 , 586 > 567 , 462 > 449
c) If the digits at Hundred-place and ten’s place are equal, then follow the rules of comparison of single-digit numbers.
958 > 953 , 876 > 872 , 634 > 631
Comparing 3 Digit Numbers Examples
Example1:
Compare three digit numbers 534, 345
Solution:
In 534 ,5 is in hundreds place.
3 is in the tens place.
4 is in one’s place.
In 345,3 is in the hundreds place.
4 is in the tens place.
5 is in one’s place.
since two numbers have three digits compare the hundreds place of two numbers.
5 is greater than 3.
so 534 greater than(>) 345.
Example 2.
Compare three-digit numbers 583, 526
Solution:
In 583,5 is in the hundreds place.
8 is in the tens place.
3 is in one’s place.
In 526, 5 is in the hundreds place.
2 is in the tens place.
6 is in one’s place.
since the hundreds place of both the numbers are same compare tens place.
8>2
So 583>526.
Numbers can be arranged in two ways.1) Ascending order 2) Descending Order.
Ascending Order
Ascending order means the numbers are arranged from smallest to largest. the smallest number comes first and then the largest numbers.

The numbers in ascending order are 168, 220,420,560,678,934.
Descending Order
Descending order means the numbers are arranged from largest to smallest. the largest number comes first and then the smallest numbers.
How to arrange 3-Digit Numbers in Descending Order?
