� To form the smallest number by some given digits, write the digits in
ascending order.

� To form the greatest number by some given digits, write the digits in
descending order.

Now let us consider the digits 4, 0 and 6. Challenge

With 4 in the hundreds column: 406 and 460 How many 3-digit
numbers can be make
With 6 in the hundreds column: 604 and 640 by 7, 0 and 3?

0 cannot be there in the hundreds place as the number will then become

a 2-digit number.

Thus, the numbers formed are 406, 460, 604 and 640.

Here, the smallest number = 406

The greatest number = 640

Form all possible 3-digit numbers using the following digits.

(a) 5, 2, 7 ______________________________________

(b) 6, 1, 3 ______________________________________

(c) 3, 0, 8 ______________________________________
