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.

What do you do with the decimal point when multiplying?
When you multiply decimals first you should take away the decimals and just leave the number. Then multiply the two numbers together and you get a larger number than the two numbers you have. Then you have to count out how many decimals places you orignally had in both of the numbers then you put how every many decimal place in the first two numbers in the answer. Let me show you an example 34.56 x 76.096 Take away the decimals 3456 x 76096 Find the answer to this 262987776 Now go back to your two original numbers and find how many decimals places they each have 34.56 has 2 decimals 76.096 has 3 decimals Since you have 2 and 3 decimals you have to put 5 decimal places in your final answer 2629.87776 this is your answer
When multiplying two factors each with one decimal place how many decimal places should the answer have?

What is the hundredths place in decimals?

When multiplying a number by 10 move the decimal to the right. when multiplying a number by 0.1 move the decimal to the left. Why?
This is because we count in tens so that the place value of a digit is ten times the place value of the digit to its right.
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.
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 can you use an estimate to help you place the decimal point in multiplying decimals?
0.235 * 0.6891 = 0.1619385 What's to estimate? The total decimal places in the multiplicands is the total in the answer.
Where do you place the decimal in the answer when multiplying decimals?

What is similar about when you multiply decimals and divide decimals by a power of ten?
Both multiplication and division can be performed simply by moving the decimal point of the number: to the right if multiplying, to the left if dividing. E.g. for 10, you can move the decimal point by one place to perform the operation. Multiplication by 10: move decimal one place to the right (add zero if already a whole number). Division by 10: move decimal point one place to the left (one place in if a whole number).
When multiplying decimals with whole numbers do you line up the whole numbers?
Hey awesome Question. The answer is no you do not have to line up the decimals when multyping only when adding and subtracting. The main thing is when you multiply make sure you put the decimal in the right place in your answer. YOu count how may places their are behind the decimals in BOTH numbers then you make sure their are that many places behind the decimal in you answer. :)

5.8 multiplied by 8.7?
When you are multiplying two numbers with decimals, it's easy to do.First, multiply the numbers as if there were not decimals there:~5.8x8.7____~406464_____5046... then, count the number of places for the decimal points, and add them together. 5.8 = 1 decimal place, 8.7 = 1 decimal place, the two added together are 2 decimal places. So your answer, 5046 needs to have two decimal places; or 50.46(I'm sorry, I had to use a ~ to keep spacing correct... I'm having problems pushing a nbsp into the code... lol)
