Which of the two rational numbers is greater in the given pair?
(i) 
or 0 (ii)
or 0 (iii)
or
(iv)
or
(v)
or
(vi)
or
(i) 
is a positive number and all positive numbers are greater than 0.
Therefore, 
(ii) 
is a negative number and all negative numbers are less than 0.
Therefore, 
(iii) Both 
and 
have the same denominator 4.
Therefore, we can directly compare both the numbers.
Since, 1 > -3
Therefore, 
(iv) Both 
and 
have the same denominator 7.
Therefore, we can directly compare both the numbers.
Since, -4 > -5
Therefore, 
(v) 
and 
have different denominators.
Therefore, we take LCM of 3 and 4 that is 12.
Now,
And,
Since, 9 > 8
Therefore, 
Hence, 
(vi) We can write 
and 
have different denominators.
Therefore, we take LCM of 1 and 2 that is 2.
Now,
And,
Since, -1 > -2
Therefore, 
Hence,
