One day, as soon as Little Bear set up the fish stall, the fox, the black dog and the old wolf came. When the bear saw a customer coming, he hurriedly called, "Buy fish? I just caught this fish. How fresh! " The fox turned the fish over and asked, "How much is a kilogram of such fresh fish?" "The bear grinned." Cheap, four yuan a kilo. The old wolf shook his head: "I am old and my teeth are falling out." I just want to buy some fish. "The bear looked reluctant:" I sold the fish to you, and who sold the fish head and tail? The fox wagged his tail and said, "Yes, no one wants to buy the leftovers, but Uncle Wolf has bad teeth and can only eat some fish. To tell you the truth, Black Dog and I are very good to each other. If you buy fish heads and tails, won't you help Uncle Wolf and Brother Xiong? "The bear clapped his hands, but he hesitated." Good, but at what cost? "The fox rolled his eyes and replied," 2 yuan is 1 kg, fish head and fish tail are 1 yuan is 1 kg. Isn't it 4 yuan 1kg? "The bear drew a picture on the ground with a stick, and then patted his thigh:" OK, let's start! " "The four of them started work together, and in a short time, the head, tail and body of the fish were separated. Once the bear weighed, the body of the fish was 35 kilograms of 70 yuan; Fish head 15 Jin 15 yuan, fish tail 10 Jin 10 yuan. The wolf, the fox and the black dog quickly ran to the Woods with the fish, matched the head, the body and the tail, and then divided them equally.
On the way home, Bear thought: According to 4 yuan 1 kg, I should sell 60 kg of fish to 240 yuan, but now I only sell 95 yuan ... Bear can't figure it out.
Do you know what this is about?
There's another one:
Fox helps.
There are 20 monkeys in the forest. They live in harmony. Good food is always shared equally by everyone and never mistreats either side.
Once, 20 monkeys picked 130 wild pears, but it was impossible to calculate how many pears each monkey should get. The monkeys were so busy for a long time that they couldn't eat pears at once. Some of them jumped around, scratching their heads.
The scene of monkeys sharing pears has long been clearly seen by a fox hiding outside. At this time, the fox swaggered towards the monkeys. "Monkey, what makes you so anxious?" Without waiting for the monkey to answer, the fox went on to say, "This is because the pears are unevenly distributed. This matter is easy to handle. Let me help, will you? "
"Great!" Several monkeys agreed without saying anything. So the fox pretended to count in detail, then counted the number of monkeys and said, "Your 130 pears are given to 20 monkey brothers. According to the formula' 130 ÷ 20', cross out a 0 after13 every time, cross out a 0 after 2, and so on. 1 pear. " The fox patted the monkey on the shoulder: "Dude is very smart. Now you all take six, and finally let me try the last one. "
"Wait!" At this time, a golden monkey jumped in front of the fox and pointed to the vertical division he wrote, saying, "In the vertical division, cross out a zero, which means that they are reduced by 10 times at the same time, so the remainder is reduced by 10 times." In this way, the score you want is not 1, but 10. "
"It turns out that the fox is not kind enough to help!" The other monkeys understood at once.
