FRACTIONSFRACTIONS
Let’s drawLet’s draw a a rectanglerectangle, and , and divide divide
itit in in twotwo equal equal partsparts......
The The redred part of the part of the rectanglerectangle represents represents a a
fractionfraction……
1/21/2 (one (one half half))
NowNow, let’s draw a , let’s draw a circlecircle and and dividedivide it in it in twotwo
equal equal partsparts......
The The redred part of the part of the circlecircle represents represents a a fractionfraction……
1/21/2 (one (one half half))
Very Good!!!Very Good!!! Now let’s Now let’s draw another draw another rectanglerectangle and and divide divide it in it in threethree
equal equal parts...parts...
TheThe redred part of the part of the rectanglerectangle represents represents
another another fractionfraction… … 1/31/3 (one(one third third))
Very Good!!!Very Good!!! Now Now let’s let’s drawdraw a a circlecircle and and dividedivide
it in it in 44 equal equal parts...parts...
The The redred part of the part of the circlecircle represents represents a a fractionfraction……
1/41/4 (o (one fourthne fourth))
Very Good!!!Very Good!!! Now you Now you know what a know what a Fraction Fraction
isis !!! !!! RememberRemember that in a that in a fractionfraction the the number number
belowbelow the the lineline indicates indicates the the total number total number
ofof equal parts equal parts in which an in which an
objectobject is is divideddivided……
and the and the numbernumber aboveabove the the lineline
indicates the indicates the numbernumber of of partsparts “selected”“selected” in in
that that objectobject......
So, So, you can represent you can represent different different fractions fractions with the with the
same same object object … For example, … For example, look look at the following at the following objectobject......
Now Now seesee how this how this rectanglerectangle can can be usedbe used to to showshow different different fractionsfractions….….
If we “If we “selectselect” ” 11 part of this part of this rectanglerectangle, What is the , What is the
fractionfraction??

fractionfraction??
