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.
There is no difference in the procedure.
0.235 * 0.6891 = 0.1619385 What's to estimate? The total decimal places in the multiplicands is the total in the answer.
There is almost no difference. The only difference is placing the decimal point.

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.
If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.

The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.
It is the multiplication of numbers where one or more of the multiplicands is in decimal form.
they aren't that different but the whole number needs to be converted for them to be the same
Multiplying decimals: Example: 2.5 x 1.3 = 3.25 Start by removing the decimal points, thus: 25 x 13 = (the answer is 325) Both 2.5 and 1.3 have 1 decimal places, so 1 + 1 = 2 (decimal places) Counting 2 places, right to left, places the decimal point here: 3.25 Search Google for division of decimals - there are plenty of how to examples and help on the internet!
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
