Describe how the placement of the decimal point changes when you multiply a number by the power of ten. How is this the same and different for division?

the answer to your question is

Recall that when you multiply a decimal by a power of ten (10, 100, 1,000, etc), the placement of the decimal point in the product will move to the right according to the number of zeros in the power of ten. For instance, 4.12 · 10 = 41.2.

hope this helps for what you needed have a nice day! :)
