题目一只鹅的重量等于2只大小相等的鸭的重量,2只鸭的重量等于3只大小相等的鸡的重量,鹅的重量是6千克。求一只鹅的重量等于几只鸡的重量?一只鸭和一只鸡的重量各是多少?分析与解:这是一道数学趣题。我们不妨用《曹冲称象》故事中的数学原理———等量代换,进行分析
The weight of a goose is equal to the weight of two ducks of equal size. The weight of two ducks is equal to the weight of three chickens of equal size. The weight of the goose is 6 kg. The weight of a goose is equal to the weight of a few chickens? What is the weight of a duck and a chicken? Analysis and Reconciliation: This is a mathematical problem. We may wish to use “Cao Chong called” the mathematical principle of the story --- equivalent substitution, analysis
