How can I correctly multiply decimals?
In order to properly multiply decimals, you need to make sure that your working is done correctly as I'm going to show you here. You want to rewrite this decimal problem out as a vertical math problem. The most important thing is that these two decimal points are lined up. Now we have two extra spaces here which we need to fill with place-holding zeros. Now that our problem is correctly set up, we're going to go ahead and multiply the decimals. Zero times five is zero. Zero times three is zero. Zero times four is zero. Zero times one is zero. We do the same here. Next we have our one and make sure that every time you're going to put a place holder every time after you multiply. One times five is five. One times three is three. One times four is four. One times one is one. Without lining up your decimal points, this is all going to be incorrect work. So now we have one last piece to do, which is as follows. Zero. Zero. Zero. Zero. Now we're going to go ahead and add. Zero. Zero. Five. Now we have a total of one, two, three, four, five, six decimal places here. So one, two, three, four, five, six. So your answer is .1435.
