Multiply a Decimal with a Whole Number


Multiplying decimals by a whole number might seem tricky but it's actually pretty simple. All you have to do is simple multiplication, actually. Read on to find out more!

Getting Started...

Let's say we have a problem such as 5.6x24. The first thing you do is put this is proper format:
   x 24

Now, just do some simple multiplication ( Forget the Decimal Point for Now )

x 56
+ 224

Now that we have our product, all we do is add in the decimal point.
Remember, count the number of digits after the decimal point. 
In this case, we have 5.6 which only has 1 digit after the decimal point
Therefore, we'll go from right to left ( decrease ) in our product one decimal place.
That means that we now have 134.4.

I know that it seems a little complex, but you'll figure it out once you've had some good practice!
