NCERT Solutions for Class 8 Maths Chapter 1 Rational Numbers Exercise 1.2

Ex 1.2 Class 8 Maths Question 1.
Represent these numbers on the number line
(i) $$\frac { 7 }{ 4 }$$
(ii) $$\frac { -5 }{ 6 }$$
Solution:
(i) $$\frac { 7 }{ 4 }$$

Here, point A represents $$\frac { 7 }{ 4 }$$ on the number line.
(ii) $$\frac { -5 }{ 6 }$$

Here, point B represents $$\frac { -5 }{ 6 }$$ on the number line.

Ex 1.2 Class 8 Maths Question 2.
Represent $$\frac { -2 }{ 11 }$$, $$\frac { -5 }{ 11 }$$ , $$\frac { -9 }{ 11 }$$ on a number line.
Solution:
We have $$\frac { -2 }{ 11 }$$, $$\frac { -5 }{ 11 }$$ and $$\frac { -9 }{ 11 }$$

Here, point A represents $$\frac { -2 }{ 11 }$$ , point B represents $$\frac { -5 }{ 11 }$$, point C represents $$\frac { -9 }{ 11 }$$
