How Is Mental Division Done

Ever wonder how is mental division done?

You can read on to find out more...

To illustrate, let us do an example of 40 / 7

Mentally solving:-

Step 1:
Break up as much as possible the original dividend 40 in term of 7 ==> (7 X 5) + 5

Step 2:
Divide the result in step 1 by original divisor 7, giving ==> (7 x 5 )/7 + 5/7 = 5 + 5/7

Remark: ( a + b ) / c ==> a / c + b / c

Answer : 5 5 / 7

-------------------------------------------------------------------**

One more example: 38 / 4

Mentally solving: 39 / 4 ==> (4 x 9) / 4 + 3/4 ==> 9 + 3/4 ===> 9 3/4

The idea is to convert the improper fraction to a mixed number.

Simple isn't it?

Maths is non-threatening if you are able to see the trick.
In fact, it becomes interesting as a result of its challenging nature.
