Interesting Math Composition (1)
There was a classmate named Wang Xiaohao. He was the king of interesting mathematics. The students admired him very much, so he became proud.
One day, Xiao Hao proudly walked up to his classmate Xiao Ling and said, "Xiao Ling, let me give you a question. How about that?"? Are you obviously fooling people? Xiaoling was unconvinced and said, "Xiaohao, I will also test you a question." "Say! There is no question that my math king can't answer!" "Listen! When 2 is greater than 5, 5 is greater than 0, and 0 is greater than 2 at the same time?" "This, Two minutes have passed... What strange question is this? Let Xiao Hao ponder. oh dear! The head is about to explode. He grabbed his head and shook it vigorously. But I still can't figure out the answer. Xiaoling smiled and said, "What about it? 'The king of interesting mathematics', can't think of it?" Xiaohao said nothing. "Tell you what." Xiaoling pointed to Xiaohao and made a gesture, saying: "Ha ha, it's time for scissors, stone and cloth!" Xiaohao was stunned: "Ah! Is there such a question?" "Why? Can't it?" "Yes... Yes." "You are so arrogant that you will lose!" Xiaohao had to nod his head and said: "It seems that I can't be complacent anymore."
As the saying goes, "Modesty makes people progress, while conceit makes people lag behind." We can't be as proud as Xiao Hao!

The fox bought onions and math The fox limped along, wondering how to get rich.
The lame fox saw that the old goat was selling onions. He went to him and asked, "Old goat, how do you sell onions? How many onions are there in all?"
The old goat said, "One kilogram of scallions costs one yuan, and a total of 100 kilograms."
The lame fox turned his eyes and asked, "How white are your scallions and how many green leaves?"
The old goat said impatiently, "For a green onion, 20% of it is white, and the rest 80% is green onion leaves."
The lame fox broke his fingers and calculated, saying, "I'll give you seven cents for a kilogram of scallion white. I'll give you three cents for a kilogram of scallion leaves. Seven cents plus three cents is exactly one yuan, OK?"
The old goat thought for a while and thought that the fox was right, so he agreed to sell it to him. The fox smiled and began to count the money.
The fox first listed a formula:
0.7 × 20+0.3 × 80=14+24=38 (yuan), and then said: "100 kg of green onion, 20% of which is green onion white, is 20 kg. 1 kg of green onion white, 7 cents, is 14 yuan in total; 80% of which is green onion leaves, 80 kg, 3 cents, is 24 yuan in total. All together, it is 38 yuan. Right?"
The old goat had been calculating for a long time, but he couldn't figure it out, so he had to say, "If you are right, you can."
"My fox never fools people! Here is 38 yuan, count it!" The fox handed the money to the old goat. When the old goat went home after selling onions, he always felt that the money was a little less, but where was it? I can't think of it. He looked down and saw the little mole coming out of the ground. He asked the mole to help him figure out the account.
The little mole said, "You used to sell scallions for one yuan per kilogram. If you have 100 kilograms, you should sell them for 100 yuan. Why does the lame fox only give you 38 yuan?"
The old goat nodded, knowing that he had suffered. But he did not understand how he suffered?
The mole said, "The fox gave you 7 cents for 1 kilogram of onion white and 3 cents for 1 kilogram of onion leaf, which is only 1 yuan for 2 kilograms. You have already suffered half of the loss."
The old goat asked, "If I lose half of my money, I should get 50 yuan. How come I only get 38 yuan?"
The mole wrote a formula:
(1 － 0.7) × 20 ＋ (1 － 0.3) × 80 ＝ 6 ＋ 56 ＝ 62 (yuan). "You lose 0.3 yuan per kilogram of scallion white, 6 yuan per kilogram of 20 scallion leaves, 0.7 yuan per kilogram of scallion leaves, 56 yuan per kilogram of 80 scallion leaves, which adds up to 62 yuan less."
The old goat turned around and ran back. He saw that the fox was selling onions for 2 yuan per kilogram. Without saying a word, the old goat bowed his head and put his horn against the lame fox's back and pushed him into the pond.
