One way we could solve this is to multiply 18 by 19, (342) then convert our numerators to their new denominator (342) so your problem would look like this:
114/342 + 54/342 = 168/342 which simplifies to 28/57, or twenty-eight fifty-sevenths.
One half is nine eighteenths. Nine eighteenths minus three eighteenths is six eighteenths, which is also one third.
