Question

Explain how to mentally multiply
a decimal number by 100.

Answer 1

Answer:

Move the number twice

Step-by-step explanation:

I find it easiest if you add extra zeros to the front of the decimal place.

or cancel out the zeros, if you had 3 zeros in the number and was multiplying it by 100, 100 has 2 zeros and the decimal has 3 so in your head cross out the zeros.
