26.
Write down the greatest 6-digit number and the smallest 7-digit number.
27.
Write the greatest 7-digit number and the smallest 8-digit number.
1.
Given, numbers are 819, 5240, 890 and 6249.
To convert numbers into descending order, we arrange numbers greatest to the smallest.
Now, descending order is 6249 > 5240> 890> 819.
2.
For getting the smallest number, firstly we convert the numbers into ascending order.
The smallest 4-digit number is 2478.
For getting greatest number, firstly we convert the numbers into descending order.
The greatest 4-digit number is 8742.
3.
Given digits are 9, 0 and 5.
Here, descending order of the given digits is 9, 9, 5, 0. [∵ greatest digit 9 is taken twice]
∴ Greatest 4-digit number = 9950
and ascending order of the given digits is 0,0, 5, 9. [∵ smallest digit 0 is taken twice]
But 0059 is a 2-digit number, because 0 at first two leftmost places is meaningless. So, keeping 5 (instead of 0) at the leftmost place and taking the smallest digit o twice i.e. 5009.
∴ Smallest 4-digit number = 5009
4.
Given digits are 0, 4 and 9.
Here, descending order of the given digits is 9, 9, 4, 0. [∵ greatest digit 9 is taken twice]
∴ Greatest 4-digit number = 9940
and ascending order of the given digit is 0, 0, 4, 9. [∵ smallest digit 0 is taken twice]
But 0049 is a 2-digit number, because 0 at first two leftmost places is meaningless. So, keeping 4 (instead of 0) at the leftmost place and taking the smallest digit o twice, we get 4009.
∴ Smallest 4-digit number = 4009.
5.
Given digits are 8, 5 and 1.
Here, descending order of the given digits is 8, 8, 5, 1. [∴ greatest digit 8 is taken twice]
∴ Greatest 4-digit number = 8851
and ascending order of the given digits is 1, 1, 5, 8. [∴ smallest digit 1 is taken twice]
∴ Smallest 4-digit number = 1158.
6.
The remaining blanks are shown as below with appropriate number, name and expansion:
| Number | Number name | Expansion |
| 50000 | Fifty thousands | 5 \(\times\) 10,000 |

8.
We know that,
1 crore = 10000000 (in digits) = 10 \(\times\) 1000000
= ten \(\times\) one million (in number name)
∴ 1 crore = ten millions
9.
