Forming the Greatest and Smallest 7-digit Numbers:
To form the greatest and smallest 7-digit numbers using the digits 4, 7, 0, 2, and 1, we need to arrange these digits in different ways.
Forming the Greatest Number:
To form the greatest number, we need to place the digits in descending order from left to right.
The digit 7 is the greatest among the given digits, so it will be placed in the millions place (leftmost place).
Next, we have the digit 4, which is the second greatest, so it will be placed in the hundred thousands place.
Next, we have the digit 2, which is the third greatest, so it will be placed in the ten thousands place.
Next, we have the digit 1, which is the fourth greatest, so it will be placed in the thousands place.
Next, we have the digit 0, which is the smallest among the given digits, so it will be placed in the hundreds place.
Finally, we have the digit 0 again, which will be repeated in the tens and units places.
Therefore, the greatest 7-digit number formed using the digits 4, 7, 0, 2, and 1 is 742,1000.
Forming the Smallest Number:
To form the smallest number, we need to place the digits in ascending order from left to right.
The digit 0 is the smallest among the given digits, so it will be placed in the millions place.
Next, we have the digit 0 again, which will be repeated in the hundred thousands and ten thousands places.
Next, we have the digit 1, which is the third smallest, so it will be placed in the thousands place.
Next, we have the digit 2, which is the second smallest, so it will be placed in the hundreds place.
Finally, we have the digit 4, which is the greatest among the given digits, so it will be placed in the tens place.
Therefore, the smallest 7-digit number formed using the digits 4, 7, 0, 2, and 1 is 100,0240.
Number Name in International System:
In the International System, the number 742,1000 is read as "seven hundred forty-two thousand, one hundred."
Similarly, the number 100,0240 is read as "one hundred thousand, two hundred forty."
These are the ways to represent the greatest and smallest 7-digit numbers formed using the given digits.
