The Interesting Story of Kneeling and Asking for Fractions Historical Stories Origin!!!!! Emergency.

Here's a fun story about fractions:

Once upon a time, there was a mathematician named Mark who was very fond of studying fractions. One day, he was working on a very complex fraction, but he had a problem that he couldn't simplify it. So he decided to consult his teacher.

His teacher looked at the fraction and told him, "This fraction is like a complex cake recipe, and you need to carefully separate each part to understand its essence." ”

Marco listened to his teacher and began to carefully analyze each part of the fraction. He found that if the numerator and denominator of this fraction were broken down into prime factors, and then multiplied by these prime factors, a very simple result could be obtained.

Marco was very happy that he had finally solved the problem. He used this method for other complex fractions and found it very useful. Since then, he has become an expert in the study of fractions and has taught the method to many more people.

Now, let's use Mark's method to simplify a fraction. For example:

We need to simplify DFRAC

First, the numerator and denominator are decomposed into prime factors, respectively:

30 = 2 \times 3 \times 5$

60 = 2 \times 2 \times 3 \times 5$

Then, multiply these prime factors by :

The result of multiplication is: dfrac =

Untie your hands: In the rise of the medieval triangle, blacks were sold in large numbers, transported by boat on the way, and blacks were tied with their hands to prevent them from escaping, so when the blacks wanted to go to the toilet, they shouted to the administrator: ", untie your hands!" So later, the release evolved into the meaning of going to the toilet.

Fun Math: Li Bai.

Carrying the pot to make wine, seeing the store doubled, seeing the flowers and drinking a bucket, three times meeting the shop and flowers, drinking all the wine in the pot, asking: How much wine is in the pot?

Answer: Let the original wine in the pot be x

Analysis: First time I saw the shop and flowers: x+x-1

The second time I saw the shop and flowers: x+x-1-1

The third time I saw the shop and the flower: [(x+x-1)+(x+x-1-1)]-1, so the equation is:

x+x-1）+（x+x-1-1）+[x+x-1）+（x+x-1-1）]-1=0

2x-1）+（2x-2）+[2x-1）+（2x-2）]-1=04x-3+（4x-3）-1=0

8x-7=0

x=7/8

Interesting math traces: Li Bai went to play wine in the pot, doubled the store when he saw it, saw that Brother Hua was worthy of drinking a bucket, met the shop and the flower three times, drank all the wine in the pot, and asked: How much wine is in the pot?

Answer: Let the original wine in the pot be x

Analysis: First Sight of the Store and Celery: x+x-1

The second time I saw the shop and flowers: x+x-1-1

The third time I saw the shop and the flower: [(x+x-1)+(x+x-1-1)]-1, so the equation is:

x+x-1）+（x+x-1-1）+[x+x-1）+（x+x-1-1）]-1=0

2x-1）+（2x-2）+[2x-1）+（2x-2）]-1=04x-3+（4x-3）-1=0

8x-7=0

x=7/8

Interesting math knows: Li Bai went to the pot to drink, doubled the store when he saw it, drank a bucket when he saw the flowers, met the shop and the flowers three times, drank all the wine in the pot, and asked: How much wine is in the pot?

Answer: Let the original wine in the pot be x

Analysis: First time I saw the shop and flowers: x+x-1

The second time I saw the shop and flowers: x+x-1-1

The third time I saw the shop and the flower: [(x+x-1)+(x+x-1-1)]-1 Therefore, the list of square books imitates the program for auspiciousness:

x+x-1）+（x+x-1-1）+[x+x-1）+（x+x-1-1）]-1=0

2x-1）+（2x-2）+[2x-1）+（2x-2）]-1=04x-3+（4x-3）-1=0

8x-7=0
