Comparing Numbers

Greater Number:

If the number of digits in the given numbers are not the same then the numbers with Greater Number of Digits is treated as a greater number. 

e.g: 7, 493, 79, 2401

Here 2401 is a 4 digit number having a greater number of digits compared to other give numbers.

so 2401 is the greater number here.

If the number of digits in the given numbers are same then compare the first digit number from the left in each given number.

the number with a greater number in the first place is treated as a greater number.

e.g: 143, 247, 947, 506 

Here 9 is greater than 1, 2, 5 so 947 is the greater number.

If the first place from the left is filled with the same number for all the given numbers then compare the numbers in the 2nd place from the left and so on.

e.g: 648, 607, 673, 619

Here the first place is filled with 6 only then compare the 2nd place, 7 is greater number compared to 4,0 so 673 is the greater number from the given number.

Arrangement of numbers from the smallest to the largest is called the ascending order.

e.g: 4, 48, 456, 5487

Arrangement of numbers from the largest to the smallest is called the descending order.

e.g: 5487, 456, 48, 4.

a) Find the greatest and smallest 4 digit numbers for the following

i) 1, 7, 9, 8

sol. smallest = 1789

      greatest = 9871 

ii) 5, 1, 6, 4

sol. smallest = 1456

      greatest = 6541

iii) 0, 9, 5, 2

sol. smallest = 2059

       greatest = 9520

iv) 4, 0, 2, 3

sol.  smallest = 2034

       greatest = 4320

b) Use any number for the maximum of two times

i) 1, 4, 5

sol.  smallest = 1145

       largest = 5541

ii) 7, 2, 6

sol.  smallest = 2267

       largest = 7762

iii) 0, 4, 7

sol.  smallest = 4007

       largest = 7740

iv) 0, 9, 6

sol.  smallest = 6009

       largest = 9960

c) Find the largest smallest 5 digit numbers for the following use all the numbers to a maximum of 3 times

i) 4, 1, 6

sol.  smallest = 11146

       largest = 66641

ii) 5, 9, 7

sol.  smallest = 55579

       largest = 99975

iii) 0, 2, 7

sol.  smallest = 20007

       largest = 77720

iv) 0, 6, 3

sol.  smallest = 30006

       largest = 66630
