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.
one third, six eighteenths, twelve thirtysixths...
1/3

Oh, dude, you're hitting me with some fractions now? Alright, so six eighteenths is the same as three eighths when simplified. You just divide the top and bottom by 2 until you can't anymore. Easy peasy, lemon squeezy.
