The first players were goats and foxes. After the game started, the goat and the fox suddenly attacked and defended, playing very fiercely. Looking at the little white rabbits, they cried out in surprise from time to time: "Good shot!" " The score went up, and soon the goat beat the first two games 2-0.
The third game began again, and the goat played harder and harder, and soon opened the score. Far away, I saw that the scoreboard had shown 20: 4. Then the fox raised his hand and asked for a time-out. The fox wiped a sweat and said to the referee elephant out of breath, "According to the nature of the ratio, 20 ∶ 4 = 5∶ 1, let's simply continue the ratio from 5∶ 1." The elephant thought for a moment and said decisively, "no, your request is unreasonable." You can't continue the game at 5: 1 or 20: 4. " When the fox's trick was seen through by the elephant, he suddenly became dejected and despondent. But the little white rabbit who is watching is puzzled. What the fox said can't be said to be unreasonable. Just as the white rabbit hesitated, the elephant referee announced that the goat had won the fox 3-0.
After the game, the white rabbit came to consult the elephant. "Excuse me, Mr. Referee, how can the fox's words be unreasonable?" The elephant said, "That's the fox's trick. 20∶4 means the difference of 16 points. In sports competitions,' several-to-several' is a difference relationship rather than a multiple relationship, that is to say,' several-to-several' on the scoreboard does not have the meaning of' ratio' in mathematics. " After listening to it, the little white rabbit suddenly realized, and said to himself, "There are so many tricks of the fox."
