Representing fractions on number line shows the intervals between two integers which will help us to increase the basic concept on formation of fractional numbers.
1. Represent the fractions: 2/5, 11/5, 8/5 and 3/5 on a number line.
Since, the denominator of each given fraction is 5; divide the space between every pair of two consecutive integers (on the number line) in 5 equal parts. Each part so obtained will represent the fraction 1/5 and the number line obtained will be of the form:
To mark 2/5; move two parts on the rightside of zero.
To mark 11/5; move eleven parts on the rightside of zero.
To mark 8/5; move eight parts on the leftside of zero.
To mark 3/5; move three parts on the leftside of zero.
The following diagram shows markings
of fractions 2/5, 11/5, 8/5 and 3/5 on a number line.
2. Represent the following fractions: 1/4, 7/4, 3/4 and 9/4 on a number line.
Since, the denominator of each given fraction is 4; divide the space between every pairs of two consecutive integers (on the number line) in 4 equal parts. Each part so obtained will represent the fraction 1/4 and the number line obtained will be of the form:
To mark 1/4; move one part on the rightside of zero.
To mark 7/4; move seven parts on the rightside of zero.
To mark 3/4; move three parts on the leftside of zero.
To mark 9/4; move nine parts on the leftside of zero.
The following diagram shows markings of fractions 1/4, 7/4, 3/4 and 9/4 on a number line.
3. Draw a number line to represent fractions: 3/8, 5/8, 1 3/8, 7/8
Since, the denominator of each given fraction is 8; divide the space between every pairs of two consecutive integers (on the number line) in 8 equal parts. Each part so obtained will represent the fraction 1/8 and the number line obtained will be of the form:
To mark 3/8; move three parts on the rightside of zero.
To mark 5/8; move five parts on the rightside of zero.
To mark 1 3/8 i.e. 11/8; move eleven parts on the leftside of zero.
To mark 7/8; move seven parts on the leftside of zero.
The following diagram shows markings of fractions 3/8, 5/8, 1 3/8, 7/8 on a number line.
So, in representing fractions on number line we have learnt how to draw any fractional points on the number line.
