B: Dividing the number by 1000
Suppose we start with the number
1000.
Moving the decimal point 3 places to the left gives ...
1.000
This number is a factor of 1000 smaller than the original—what you'd expect to get when you divided by 1000.
On dividing the given number by 1000 or [tex]10^3[/tex], the decimal point will shift 3 places to the left in the decimal expression of the number. Option B is correctly matched.
It is required to find a number that should be divided to move the decimal point 3 places to the left in the decimal number.
For a single shift of decimal from right to left, 10 is divided from the number.
So, for 3 displacements, 1000 or [tex]10^3[/tex] should be divided from the number.
Therefore, on dividing the given number by 1000 or [tex]10^3[/tex], the decimal point will shift 3 places to the left in the decimal expression of the number. Option B is correctly matched.
