FRACTIONS
Let’s draw a rectangle,
and divide it in two
equal parts...
The red part of the rectangle
represents a fraction…
1/2 (one half)
Now, let’s draw a circle
and divide it in two equal
parts...
The red part of the circle
represents a fraction…
1/2 (one half)
Very Good!!! Now let’s
draw another rectangle
and divide it in three
equal parts...
The red part of the
rectangle represents another
fraction… 1/3 (one third)
Very Good!!! Now let’s draw
a circle and divide it in 4
equal parts...
The red part of the circle
represents a fraction…
1/4 (one fourth)
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…
and the number above
the line indicates the
number of parts
“selected” in that
object...
So, you can represent different
fractions with the same object …
For example, look at the
following object...
Now see how this rectangle can
be used to show different
fractions….
If we “select” 1 part of this
rectangle, What is the fraction?
If we “select” 1 part of this
rectangle, What is the fraction?
