FRACTIONS
2
Lets draw a rectangle, and divide it in two
equal parts...
3
• The red part of the rectangle represents a
fraction
• 1/2 (one half)

4
Now, lets draw a circle and divide it in two
equal parts...
5
• The red part of the circle represents a fraction
• 1/2 (one half)

6
Very Good!!! Now lets draw another rectangle and
divide it in three equal parts...
7
• The red part of the rectangle represents another
fraction 1/3 (one third)

8
Very Good!!! Now lets draw a circle and divide
it in 4 equal parts...
9
• The red part of the circle represents a fraction
• 1/4 (one fourth)

10
Very Good!!! Now you know what a Fraction is
!!! Remember that in a fraction the number
below the line indicates the total number of
equal parts in which an object is divided
11
and the number above the line indicates the
number of parts selected in that object...
12
So, you can represent different fractions with
the same object For example, look at the
following object...
13
Now see how this rectangle can be used to show
different fractions.
14
If we select 1 part of this rectangle, What is
the fraction?
15
If we select 1 part of this rectangle, What is
the fraction?
1 ----- 4
16
If we select 2 parts of this rectangle, what is
the fraction?
17
If we select 2 parts of this rectangle, what is
the fraction?
2 ------- 4
18
If we select 3 parts of this object, what is
the fraction?
19
If we select 3 parts of this object, what is
the fraction?
3 ------- 4
