Simplify each ratio for each person.
For Victor, the ratio of sand dollars to starfish is: 12/20, simplified, it becomes 3/5 (divide 4 from numerator & denominator)
For Cheyenne, the ratio of sand dollars to starfish is: 8/16, simplified it becomes 1/2 (divide 4 8 from numerator & denominator)
3/5 > 1/2, therefore, Victor has the higher ratio.
