Answer:

The number is 7,122.

Explanation:

This is simply a question of place value.

The concept of place value explains that the position a digit is within a number affects its value. Now the digit has several value slots which it can occupy within a number.

Let me use the number 7, 654, 321 to demonstrate this:

The digit 1 occupies the unit place; hence it has a value of 1

The digit 2 occupies the tens place; hence it has a value of 20

The digit 3 occupies the hundreds place; hence it has a value of 300

The digit 4 occupies the thousands place; hence it has a value of 4000

The digit 5 occupies the tens of thousands place; hence it has a value of 50,000

The digit 6 occupies the hundreds of thousands place; hence it has a value of 600,000

The digit 7 occupies the millions place; hence it has a value of 7,000,000

Therefore, to make the digit 7 in the number 1,227, one thousand times larger than it is, we have to move the place value of the digit to the thousands position.

This will make the number 7,122.

in 1,227, seven has a value of only 7 units, but in 7,122. seven has a value of 7,000
