Subtract the first rational number from the second in each of the following:
(i) 
(ii) 
(iii) 
(iv) 
(v) 
(vi) 
(vii) 
(viii) 
(i) 
- 
= 
= 
(Therefore, L.C.M of 8 and 8 is 8)
= 
(ii) 
- 
= 
= 
(Therefore, L.C.M of 9 and 9 is 9)
(iii) 
- 
= 
= 
(Therefore, L.C.M of 11 and 11 is 11)
(iv) 
- 
= 
= 
(Therefore, L.C.M of 13 and 13 is 13)
(v) 
- 
= 
= 
(Therefore, L.C.M of 8 and 4 is 8)
(vi) 
- 
= 
= 
(Therefore, L.C.M of 6 and 3 is 6)
= 
(vii) 
- 
= 
= 
(Therefore, L.C.M of 14 and 7 is 14)
(viii) 
- 
= 
= 
(Therefore, L.C.M of 22 and 33 is 66)
