The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.
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.

The difference is that if you multiply with a whole number and then multiply with a decimal and you compare.You will notice the whole number is greater.You are very welcome.
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
You don't move the decimal point at all. You just multiply the numbers and the point should sort itself out or be put of how many digits it is to be.
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.
why does multiplying numbers by ten move the decimal point to the right
It is not. When multiplying two whole numbers you need not be concerned about placing the decimal point in the answer.
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.
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.
Yes. You first multiply, then however many decimal places you were multiplying, you move over.
0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
