NCERT Solutions for Class 8 Maths Chapter 1 Rational Numbers Ex 1.2
Question 1.
Represent these numbers on the number line.
(i) (frac { 7 }{ 4 } )
(ii) (frac { -5 }{ 6 } )
Solution.
(i) (frac { 7 }{ 4 } )
We make 7 markings of distance (frac { 1 }{ 4 } ) each on the right of 0 and starting from 0. The seventh marking represents (frac { 7 }{ 4 } )
(ii) (frac { -5 }{ 6 } )
We make 5 markings of distance (frac { 1 }{ 6 } ) each on the right of 0 and starting from 0. The seventh marking represents (frac { -5 }{ 6 } )
Question 2.
Represent (frac { -2 }{ 11 } ,frac { -5 }{ 11 } ,frac { -9 }{ 11 } ) on the number line.
Solution.
We make 9 markings of distance (frac { 1 }{ 11 } ) each on the left of 0 and starting from 0.
The second marking represents (-frac { 2 }{ 11 } ) the fifth marking represents (-frac { 5 }{ 11 } ) and the ninth marking represents (-frac { 9 }{ 11 } )
Question 3.
Write five rational numbers which are smaller than 2.
Solution.
Five rational numbers which are smaller than 2 are 1, (frac { 1 }{ 2 } ),0, -1, (-frac { 1 }{ 2 } )
Question 4.
Find ten rational numbers between (-frac { 2 }{ 5 } ) and (frac { 1 }{ 2 } )
Solution.
Question 5.
Find five rational numbers between:
Solution.
Question 6.
Write five rational numbers greater than -2.
Solution.
Five rational numbers greater than -2 are:
(frac { -3 }{ 2 } ), -1, (frac { -1 }{ 2 } ), 0, (frac { 1 }{ 2 } )
There can be many more such rational numbers
Question 7.
