Just follow these steps: 1. Multiply normally, ignoring the decimal points. 2. Thenput the decimal point in the answer - it will have as many decimal places as the two original numbers combined. In other words, just count up how many numbers are after the decimal point in both numbers you are multiplying, then the answer should have that many numbe...
Because when you multiply without the decimal point, you are really shifting the decimal point to the right to get it out of the way: Then we do the (now easy) multiplication: 3. × 11. = 33. But remember, we did 3 Moves of the decimal point, so we need to undo that: Here are some more examples:

And that's all. Just remember: the answer should have the same number of decimal places as are in both the numbers you are multiplying.
When multiplying decimals, add up the number of digits after the decimal points in the question. This number tells you the number of decimal places you should have in your answer. So, if the ...

For example, follow these steps to find the product of 1.21 x 3: Multiply the 1 in 1.2 1 by 3 to get 3. Write 3 below the rightmost column.
Example 1: multiplying an integer by a decimal. Work out. 6 × 5.2. Multiply any decimal numbers by an appropriate power of ten to make them whole numbers. Multiply 5.2 by 10 to make it 52. 2 Use column multiplication (or another preferred method) to find the product of the numbers. 6 × 52 = 312.

Example 1: multiplying a decimal number by a decimal number. Find the product of 0.8 × 0.40.8 × 0.4. Stack the number with the most digits on top. Both factors have the same number of digits, so it does not matter which one is on top. 2 Multiply as if the numbers were multi-digit whole numbers, regrouping when necessary.
