Which is the same as moving the decimal point 3 places to the left in a decimal number a: dividing the number by 100 b: dividing the number by 1000 c: multiplying the number by 100 b: multiplying the number by 1000

On dividing the given number by 1000 or , 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 should be divided from the number.

Therefore, on dividing the given number by 1000 or , the decimal point will shift 3 places to the left in the decimal expression of the number. Option B is correctly matched.

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.
