INTRODUCTION OF DECIMAL

__Introduction of Decimal Number__

**Decimal number system
is a system where we can calculate length, height, width, distance…etc of any
object via addition, multiplication, subtraction,and division.**

**You can observe the whole
circle is divided into 10 parts or proportion, From this picture we can say
that, each portion is one of ten or one tenth ( 1/10 ) of Whole circle areas.**

**In the above picture, we
have divided the entire rectangle by 20 triangular parts and Out of which 2 only
colored. So, these two triangles take the 2/20 area of total rectangular part.**

**We can say, each part
of the rectangular called one tenth and it will be written like**

** 1**

** =
--------**

** 10**

**Now we have to
understand the process of execution of Decimal. The decimal process is identified
or justified by point ‘ . ‘ and the position of point ‘ . ‘ decides the value of the number.**

**If we wish to add the above fraction like 1/10 with 1/10…… or 1/100 with 1/100….. or 1/10 with
1/100….. , the process will be complicated.**
