Final answer:
The world's largest fruitcake weighing 4,353 kg could serve 21,765 people, with each serving being 200 grams after converting the weight to grams and dividing by the serving size.
Step-by-step explanation:
To calculate how many servings the world's largest fruitcake could provide, we divide the total weight of the cake by the serving size. The fruitcake made by Dr.Fabrizio Sepe weighed 4,353 kg, and if one serving is 200 grams, we first need to convert kilograms to grams to make the units consistent.
Since 1 kilogram equals 1,000 grams, the fruitcake, therefore, weighed 4,353 kg * 1,000 grams/kg = 4,353,000 grams. Next, we divide the total weight by the serving size:
4,353,000 grams ÷ 200 grams/serving = 21,765 servings
Therefore, the fruitcake could serve 21,765 people, each getting a 200-gram slice.
