The Monkey King skillfully explained the story of proportional mathematics.
The source of life is full of interest in mathematics. Here I have compiled some math stories of primary school students in Jinan, hoping that parents and children in Jinan can understand and fall in love with math in happiness.

Math Story of Pupils: the Monkey King Cleverly Solves the Problem of Proportion.

It is said that the Tang Priest and his disciples went to the Western Heaven to learn from all sentient beings, and it was difficult for ordinary people to go through the eighty-one difficulty. After a day's walk, the master and apprentice felt tired and rested. Bajie lost his rake and fell asleep. The Tang Priest meditated with Friar Sand, and Wukong danced the golden hoop.

I saw Wukong "changed", and the golden hoop changed from the original "embroidery needle" to a towering "big pillar". Wukong shouted, "Bajie, guess how long my golden cudgel is now?" Pig said lazily, "How long will it last? Only 10 meter. " Wukong said, "My golden cudgel is awesome. It can change 10 meter in 5 seconds. " "That 25 seconds can be changed to 15 meters," Bajie said casually. Friar Sand said, "There must be some mistake. Five seconds is less than 15 meter, and 25 seconds is more than 15 meter ... "Pig said," Nonsense, this reason is not sufficient at all. " Wukong said, "Then I'll tell you the reason and convince you." "I'd like to hear the details," Pig said. Wukong said, "By solving the ratio, for example, 25 seconds can be exchanged for x meters, and the ratio is 5: 10 = 25: X, 5x=250, and x=50. The answer should be 50 meters! " "This ... this ..." The pig was speechless. "There is another way." Friar Sand added, "Five seconds can become 10m, 1 0 ÷ 5 = 2m, which means1sec can become 2m, and 25 seconds can become 25x2 = 50m. Bajie seemed to wake up and said "Yes" again and again.

Hearing this, the Tang Priest said, "You are all very clever and have solved this problem in different ways. Think everything over, Bajie. You can't talk nonsense anymore. You should explain the problem with reasons. "

"Of course, of course, I will remember the teacher's teachings and study math well in the future ..." Ha, ha, ha, and the four of them set off again with a smile.
