Final answer:
To find the fraction of a dollar that each winner received, divide the total amount of money by the number of winners and round to the nearest hundredth.
Step-by-step explanation:
To find the fraction of a dollar that each winner received, we divide the total amount of money ($19) by the number of winners (30).
19 ÷ 30 ≈ 0.6333
Rounded to the nearest hundredth, each winner received approximately $0.63.
Therefore, the correct answer is B) $0.63.
