Question 1.
Solution:
(i) Rational numbers: The numbers of the form \(\frac { p }{ q }\) where p and q are integers and q ≠ 0, are called rational numbers.

(iv) Yes, there is one rational number (0) which is neither positive nor negative.

Question 2.
Solution:

(viii) \(\frac { 0 }{ 1 }\) are all rational number but \(\frac { 1 }{ 0 }\) and \(\frac { 0 }{ 0 }\) are not rational number as their denominator is zero.

Question 3.
Solution:
(i) Numerator = 8, denominator =19
(ii) Numerator = 5, denominator = – 8
(iii) Numerator =-13, denominator =15
(iv) Numerator = – 8, denominator = -11
(v) Numerator = 9, denominator = 1

Question 4.
Solution:

Question 5.
Solution:
According to the definition, a rational number is positive if both of numerator and denominator have same signs. Therefore
(iii), (iv) and (vi) 8 are positive rational numbers.

Question 6.
Solution:
According to the definition, a rational number is negative if numerator and denominator have opposite sign. Therefore.
(iii), (iv), (v), (vi) are all negative rational numbers.

Question 21.
Solution:

Question 22.
Solution:
(i) False, as there is no end of smallest and largest rational number,
(ii) True.
(iii) False, as zero is a rational number but the division of zero is meaningless.
(iv) True.
(v) False, every rational is not a fraction
In a fraction, numerator and denominators is a whole number but the denominator can’t be zero
