Simplify each of the following and write as rational number of the form
:
(i) 
(ii) 
(iii) 
(iv) 
(v) 
(vi) 
(i) We have,
+ 
+ (
)
= 
+ 
- 
= 
+ 
+ 
Therefore,
L.C.M of 4, 6 and 8 is 24
= 
= 
(ii) We have,
+ 
+ (
)
= 
-
- 
= 
+ 
-
Therefore,
L.C.M of 3, 6 and 9 is 18
= 
= 
(iii) We have,
+ 
+ (
)
= 
-
- 
= 
-
-
Therefore,
L.C.M of 6, 2 and 8 is 24
= 
= 
(iv) We have,
+ 
+ (
)
= 
-
- 
= 
-
-
Therefore,
L.C.M of 5, 10 and 15 is 30
= 
= 
(v) We have,
+ 
+ (
)
= 
-
- 
= 
-
-
Therefore,
L.C.M of 15, 10 and 20 is 60
= 
= 
= 
(vi) We have,
+ 
+ (
) + 3
= 
-
- 
+ 3
= 
-
-
+ 
Therefore,
L.C.M of 3, 2, 3 and 1 is 6
= 
=
