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

When multipling decimals why does the decimal move one place to the right?
It depends on what numbers you are multiplying and how many decimals places they each have. It doesn't always haveto move to the right.
How is multiplying two decimals different from multiplying one decimal by a whole 3?
There is no difference in the procedure.
How is multiplying two decimals like multiplying a whole number and a decimal?
There is almost no difference. The only difference is placing the decimal point.
When multiplying two decimals the sum of the decimal places in the factors is?

Which method you prefer for converting decimals to percents using equivalent fractions or multiplying by 100 why?
Multiplying by 100 is easier. Just move the decimal point two places to the right.

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.
Why does multiplying numbers by ten move the decimal point to the right?

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.
What is the definition for multiplying decimals?
It is the multiplication of numbers where one or more of the multiplicands is in decimal form.
What is the difference between multiplying decimals and multiplying whole numbers?
You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (BEFORE eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.
