first u set up your problem lining up not the decimals but the last numbers. Then u multiply the last number by the number on top then go down the row multiplying.Then u start with the next number and place it under the answers to the first one and don't forget an atomatic 0 and add one every number you do. Then u add the numbers together. then u count how many numbers were behind the decimals and move ur decimal over that many places to ur answer and u get it.

How do you do multiplication problems with decimal points?
You multiply the numbers like you multiply integers. Count how many numbers are after the decimal points in both numbers combined and move the decimal point in front of the answer.
How do you multiply by a decimal?
line up the numbers and decimals multiply regularly then bring the decimal down
How do you multiply a decimal with whole and part of a whole number?
Example of multiplying whole decimal numbers: 2.37 × 3.56 = 8.4372 Remove the decimal point and multiply as for whole numbers: 237 × 356 = 84372 Then add the decimal point, thus : 8.4372
If you multiply a decimal number and a whole number will you have a decimal in the answer?
Often, yes. But it depends on the numbers. For example, if you multiply 1.5 x 2, you get 3 as the answer (whole number). But if you multiply 1.5 x 3, you get a decimal of 4.5
How do you multiply 471.5 with 21.3?

How do you multiply two-digit numbers in a decimal?
To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
When multiplying a decimal by a decimal multiply as with what numbers?
