the answer is it stays in the same place.

Suppose you want to multiply two decimal numbers A and B. Multiply the two numbers ignoring the decimal points.
Count the number of digits after the decimal point in the number A.
Count the number of digits after the decimal point in the number B.
Add these two numbers together. This is the number of digits you want after the decimal point in the answer. So count back from the end.
Example:
2.54 * 3.5 (this is number of centimetres in 3.5 inches)
254*35 = 8890
Number of digits after the decimal point in 2.54 is 2 (5 and 4).
Number of digits after the decimal point in 3.5 is 1 (5).
2 + 1 = 3 so there must be 3 digits after the decimal point in the answer.
Therefore 8890 becomes 8.890
NOW, you can simplify it to 8.89

How do you align decimals when multiplying?
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.

When multiplying a decimal by a decimal multiply as with what numbers?
The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.
Do you move decimal points over when multiplying?
Yes. You first multiply, then however many decimal places you were multiplying, you move over.
