Which of the two rational numbers is greater in the given pair?

(i)or (ii)or (iii)or


(iv)or(v)or (vi)or


(i) and have different denominators.


Therefore, we take LCM of 3 and 7 that is 21.


Now,



And,



Since, -24 > -28


Therefore,


Hence,


(ii)



and have different denominators.


Therefore, we take LCM of 9 and 8 that is 72.


Now,



And,



Since, -45 > -56


Therefore,


Hence,


(iii)



and have different denominators.


Therefore, we take LCM of 3 and 5 that is 15.


Now,



And,



Since, -5 > -12


Therefore,


Hence,


(iv)



And,



and have different denominators.


Therefore, we take LCM of 13 and 12 that is 156.


Now,



And,



Since, -91 > -108


Therefore,


Hence,


(v)



and have different denominators.


Therefore, we take LCM of 10 and 5 that is 10.


Now,



And,



Since, -7 > -8


Therefore,


Hence,


(vi)


We can write


and have different denominators.


Therefore, we take LCM of 1 and 5 that is 5.


Now,



And,



Since, -12 > -15


Therefore,


Hence,
