The math contest was held as scheduled, and many animals came to participate, even the piglets with average grades came to participate. It can be seen how attractive the prize of the final winner should be! The host this time is Uncle Panda, who stood in front of the rostrum and solemnly announced: "The 2 1 forest fun math competition begins!" At this time, warm cheers and applause rang out from the audience! Each player comes to his own venue and begins to answer questions, such as written test, oral test, time calculation and so on. These questions make the animals see things in a blur, at a loss, and don't know where to start.
After the preliminary round, there will be a rematch, and after the rematch, there will be a final. Finally, after going through five passes and six generals, I finally reached the final. Thousands of animals took part in the competition, but later, only eight small animals entered the advanced finals. These eight small animals are: dog stupid, chicken ya ya, bear cool, elephant Ming Ming, monkey smart, kitten naughty, deer flower, pig fat! These people can be described as the elite of the elite, the strong of the strong, and the pig proudly said, "Haha!" " See if you dare to look down on me and say that I am inferior to others. I must find a way to win this championship. Haha, as the old saying goes, it is better to laugh at a pig than to laugh at it. See if you dare to laugh at me! "
At this time, Aunt Peacock came over and led them to a small bamboo forest. She said to them, "There are two boards in this small bamboo forest. Let's see who can find them first and then give them to me. Who is today's champion! " All the small animals replied in unison, "I know!" " Then walked to the depths of the bamboo forest. ...
Piggy found the title board first, and it read 8 1× 12÷ 18, 35 ÷ 25× 15, 8154 ×1. ...
Piglet sat down, carefully observed these problems and found a solution. 8 1× 12÷ 18, 18 are our enemies, 8 1 and 12 are our troops, and we use the method of transferring troops from 86544.
8 1× 12÷ 18
=27×36÷ 18
=27×2
=54
Work out the first question, and the other questions will be easy to work out. Can be written down according to the first question. 35 ÷ 25× 15, 25 is our enemy, and 35 and 15 are our army. With the idea of adjusting troops, it is more vivid, more skillful and simpler to turn from 5 to 15, 15 to 75, from 35 to 7, from 75 to 25!
35÷25× 15
=7÷25×75
=7×3
=2 1
This problem can be calculated by transferring tigers on the mountain. 8 1 ÷ 54×12,54 is our enemy, and 81and 24 are our army. With the idea of shifting the mountain tiger, 54 is adjusted to 6 and 9, and 8 1 9 and 24/6 are more vivid and accurate.
8 1÷54× 12
=8 1÷6÷9×24
=9×24
=36
After the pig finished the problem, he stood up from the ground and said, "Oh dear! It's getting late, I should go to aunt peacock! " Then, the pig ran quickly. When Feifei Pig ran to Aunt Peacock, she found that all the other small animals had arrived. Let Aunt Peacock check it! The pig was anxious and said, "Aunt Peacock, check mine first, mine!" " "Aunt Peacock is still a leisurely inspector. It's finally the pig's turn. Pig quickly handed the title board to Aunt Peacock and stared at Aunt Peacock with nervous eyes. Finally, Aunt Peacock finished the inspection and announced that the accuracy was the same because of the time spent by everyone. However, the ideas and methods to solve the problem of pig obesity are novel, simple, simple, flexible and simple. Therefore, the champion of this competition is piggy fat!
