EXERCISE 1B
Fill in each of the following boxes with the correct symbol > or < :
1. 1003467 987965 2. 3572014 10235401
3. 3254790 3260152 4. 10357690 11243567
5. 27596381 7965412 6. 47893501 47894021
Solution:
(1) 1003467 > 987965
1003467 has 7-digit and 987965 has 6-digit ,
Therefore, We know that a 7-digit number is always greater than a 6-digit number.
So, 1003467 is greater than 987965.
Solution:
(2) 3572014 < 10235401
3572014 has 7-digit and 10235401 has 8-digit,
Therefore, We know that a 7-digit number is always less than a 8-digit number.
So, 3572014 is less than 10235401.
Solution:
(3) 3254790 < 3260152
The digit at lakh and ten lakh places are same in both numbers.
However, the digits at the ten thousands place in 3254790 and 3260152 are 5 and 6,
respectively.
Clearly, 5 < 6
∴ 3254790 < 3260152
Solution:
(4) 10357690 < 11243567
The digit at crore place is same in both numbers.
However, the digits at the ten lakhs places in 10357690 and 11243567 are 0 and 1, respectively.
Clearly, 0 < 1
∴ 10357690 < 11243567
Solution:
(5) 27596381 > 7965412
27596381 has 8-digit and 7965412 has 7-digit,
Therefore, We know that a 8-digit number is always greater than a 7-digit number.
So, 27596381 is less than 7965412
Solution:
(6) 47893501 < 47894021
The digit 4,7,8, and 9 are same in both numbers,
However, the digits at thousand places in 47893501 and 47894021 are 3 and 4, respectively.
Clearly, 3 < 4
∴ 47893501 < 47894021
