Dividing a whole number by a decimal looks complicated but its really easy once you practice it. Let's take the whole number 50 and lets divide it by 2.5. So what we need to do is put this problem in division form:

____

2.5/ 50

The first thing we need to do is make 2.5 into a whole number because thatis the rule when dividing with a decimal divisor:

The first thing we need to do is make 2.5 into a whole number because thatis the rule when dividing with a decimal divisor:

2.5

__x1 0__

0 0

__+2 5__

2 5

So now we have the whole number 25 and since we multiplied 2.5 by 10 we have to do the same thing with 50 like this:

__50__x 10 =

__500__

2.5 x 10 = 25

So the next thing we have to do is divide 500 by 25:

__

__20___ 25x20=500
25/ 500

__- 500__

0

So now we know that

Now try some of these and make sure to watch the video on YouTube.

__50/2.5=20__.Now try some of these and make sure to watch the video on YouTube.
