Lets say that u r doing the problem. 5.2 x 2.1 there are altogether 2 numbers to the right of the decimal, so you take out the decimals, multiply, and add the decimal 2 numbers to the left.
There is no difference in the procedure.
There is almost no difference. The only difference is placing the decimal point.

They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
You line up the decimals with the thousandths and put the decimal straight down from where it is and just add with the decimal in the same spot.
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.
There is no difference in the procedure.
There is almost no difference. The only difference is placing the decimal point.
STEP 1:Take out the points and multiply as normal. STEP 2:After multiplying,count the numbers that are after the decimal points. STEP 3:Then look at your answer and put in your decimal places from the right to the left.
0.79 4.3
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.
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.
they aren't that different but the whole number needs to be converted for them to be the same
It is in decimal form already.
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!
