Question

Which choice describes a question that could be answered by moving the decimal point 3 places to the right?

B.
multiplying 31.04 by 1,000

C.

D.

Answer 1

multiplying 31.04 by 1000 = 31040

Answer 2

The answer is B.

When we multiply by 1000, we move the decimal place 3 times to the right(or add 3 zeroes).

Just count the number of zeroes and move it that many places to the right(if it starts with '1').
