  "Add the whole numbers and fractions separately. Both fractions have the same denominator (18), so just add the numerators.",
  "Whole numbers: 1 + 6 = 7. Fractions: 1/18 + 1/18 = 2/18 = 1/9 (divide both by 2). So the sum is 7 1/9.",
  "7 1/9 is not among options A-C. Answer: D (None of the above)."
