0.5 X 10 = 5
True
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.
This is not necessarily true. 2 x 0.55 = 1.1
False. 2 x 0.55 = 1.1
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.

It is false.0.2 * 25 = 5, which has no decimal places.
If the two numbers have x and y decimal places respectively, then the raw product (before deleting and trailing 0s) has (x + y) digits after the decimal point.
When you multiply decimals, you just ignore the decimal until the end, then, to find the amount of decimal places in your answer, you add the amount of decimal places in both your factors
-- Ignore the decimal point; just multiply the two whole numbers. -- After the multiplication is done, put the decimal point back into the product. Put it in the right place so that the product has as many digits after the point as the original decimal had. If there aren't enough digits in the product to do that, add some zeros to the left end of it.
-- Multiply 73 by 8 , to get 584 .-- Count the total number of decimal places that you've ignored in both factors. (3)-- Mark off that number of decimal places (3) in the product, to get 0.584 .
