When a dumb man comes to buy meat, it is difficult to say how much money he has

A pound is less than forty, and nine taels is more than sixteen

Ask how much meat you can count

Its ten analysis: general, unit price = total price ÷ quantity.

But in the case of surplus and shortfall, the key is to understand the "ratio of sum to difference". The difference between the two purchases is 7 taels (1 catty is counted as two in the ancient arithmetic problem!) And these 7 taels need to spend 56 Wen, and 56÷7 is the ratio of the sum and difference of the two quantities.

Try it yourself!



The partition wall listens to the guest and divides the silver

I don't know the number of people, I don't know the silver

Seven taels as much as four taels

Half a pound less than ninety-two

A group of dolls sit in groups,

Divide the fruit around the table,

6 per person and 6 left,

7 less per person,

Clever friends do the math,

How many fruits are in a few dolls?

A few classmates thought about it together and didn't know where to start. At this time, a man called the old gentleman came by, and we thought he was knowledgeable, so we asked him for advice. After reading the questions, he smiled and said, 'You study the contents of the book carefully, these strange questions are not interesting.' A classmate whispered that he wouldn't either. Then we move on to the discussion.

After a while, the old gentleman saw that we were still discussing, perhaps he had thought it through, to prove that he would do it, or perhaps to be moved by our spirits, and came up and said, 'Come, I'll help you think about it. What can be substituted for fruit?' We said no, and a classmate asked if the apricot kernel was okay and he said yes. We say that I don't know how many fruits. He said, in this way, let's change the title, you 5, the title is changed to 2 per person, 2 left, 3 per person, 3 difference between 3. So take two of yeach; There are 2 left, continue to divide, 2 people get 3, because each person 3 is 3 different from 3, that is, there are 3 people who get 2, a total of several people. At this time, one of us said, "Got it, it's 5 people." It is calculated from: 2+3=5 (people). He smiled and said, "Forget the rest, and then left." A few of us went back to the original topic. In the same way, using 6+7=13 (people) to calculate that the dolls in the original question are 13 people, and the fruits are 84
