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


=


=
