" If "(3)/(4),(6)/(7),(8)/(9)" at "m" ,"R" ,"arct" ? "

The L.C.M.of (3)/(4),(6)/(7),(9)/(8) is (a) 3 (b) 6(c) 9 (d) 18

Write the set {(1)/(2),(2)/(3),(3)/(4),(4)/(5),(5)/(6),(6)/(7),(7)/(8),(8)/(9),(9)/(10)} in the set builder form.

The average of 4(3/5) , 2(2/3) , 6(8/9) , 7(7/15) , 3(5/9) is:

(5)/(6) -: (6)/(7) xx ? - (8)/(9) -: 1 (2)/(5) -: (3)/(4) xx 3 (1)/(3) = 2(7)/(9)

(3)/(2!)+(5)/(4!)+(7)/(6!)+(9)/(8!)+....=
