Need to convert them all to a common denominator before you can add them.

Since the 9 and the 3 are both factors of the 18, 18 is a good common denominator.

1/9 = 2/18

2/3 = 12/18

So your addition problem is [ (2/18) + (12/18) + (5/18) ] = 19/18 = 1 and 1/18

[latex]1/9+2/3+5/18 \\ =(2*1)/(2*9)+(6*2)/(6*3)+5/18 \\ =2/18+12/18+5/18 \\ =19/18[/latex]
