STEP 1
= 1/9 + 2/3 + 5/18
change each fraction to a common denominator; 18 is the lowest common denominator (LCD)

* to change 1/9 to LCD of 18:
18÷9= 2; multiply 2 by numerator of 1; new fraction equals 2/18


STEP 2
= 2/18 + 12/18 + 5/18
add numerators only

= (2 + 12 + 5)/18

= 19/18


ANSWER: B) 19/18

Hope this helps! :)
