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.
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.
line up the numbers and decimals multiply regularly then bring the decimal down
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
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
The same way you multiply any other decimal numbers. The result is 10,042.95.

line up the numbers and decimals multiply regularly then bring the decimal down
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.
The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.

the product will have four decimal places
The product of 0.3 and 3 is 0.9. To calculate this, you simply multiply 0.3 by 3. When multiplying a decimal by a whole number, you can ignore the decimal point temporarily and multiply the numbers as if they were whole numbers. The final product will have the same number of decimal places as the total number of decimal places in the numbers being multiplied.
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
