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 \(\frac { -9 }{ 11 }\)
