ALeast common multiple
BGreatest common divisor
CSum of both parts
DLarger of the parts
Answer & Solution
Correct answer: B. Greatest common divisor
1. Pick c as the greatest common divisor of numerator and denominator.
2. Dividing both parts by c gives the smallest possible whole-number parts.
3. The least common multiple would enlarge numbers, and sums or the larger part do not divide both evenly.
