the given expression is,\

9/12 + 3/6 + 3/9

we have denominators 12 , 6 , 9

now we take the LCM to get common denominator

LCM of 12, 6 , 9 is

12 = 3 x 2 x 2

6 = 2 x 3

9 = 3 x 3

so the LCM is 3 x 3 x 2 x 2 = 36


(9)/(12)+(3)/(6)+(3)/(9)=(9*3+3*6+3*4)/(36)
(27+18+12)/(36)=(57)/(36)

so the answer is 57
