Anonymous users2024-02-07The first question should be 27-2=25 to sum logic.
The second question is simple, if the green onion white and green onion leaves are sold separately, the sum of ** is 2 times the whole sale. It can be solved with equations. That is to say, the whole sale is 1 yuan a catty, and it is sold separately, and the green onion white ** and green onion leaves** cost a total of 2 yuan.
The third question, when I was a child, I used to do it, it should be 6 days, this number is small, use a stupid method, draw a picture and count it.
The fourth question, 14 peaches, one by one, if you let She, it is 15.

Anonymous users2024-02-061) Dizzy, 27 yuan is the money spent by the customer, 2 yuan is the money left, the equation should be:
30 = 25 (the money earned by the boss) + 2 (the money earned by the waiter) + 3 (the money returned) 3 * 9 = 25 (the money earned by the boss) + 2 (the money earned by the waiter) 2) 1 yuan a pound of green onions.
But the person who sells green onions says that they sell green onions for 7 cents white and green onions for 3 cents, that is, white 7 cents a catty, green 3 cents a catty, adding up to 1 yuan and 2 catties. The actual ** is a pound of white yuan and a pound of green yuan.
3) Climb the sky. I climbed for seven days and climbed 7m, and then climbed for a day to the wellhead, and I didn't fall down.

It should be 3 x 9 - $2 = $25 from the waiter's hideout.
The actual cost is 3 x 9 -2) = (the actual cost is 30-5) 2) green onions are sold for one yuan a catty, and the green onions are sold separately for less than one yuan, and the green onions become five cents a pound on average.
3) Five days. I climbed one meter a day, but on the fifth day I climbed seven meters and went out and didn't fall.
4) 15 pcs.
Buy ten first, exchange 9 peach pits for 3 peaches, exchange 3 peach pits for one peach, exchange the remaining two peach pits for one peach, and return the peach pit to the one who bought the peach after eating.

Anonymous users2024-02-041.The 2 yuan hidden by the waiter is in 27 yuan, which should be 25 + 3 + 2 = 30
2.The price of green onion white and green onion is wrong, and a pound of green onion can be divided into half a catty of green onion white and half a catty of green onion, so it should be yuan per half catty of green onion, and yuan per half catty of green onion.
Sky. Piece.

Anonymous users2024-02-031) The current currency situation is: 1 yuan per person for these 3 people, 2 yuan for the waiter, and 25 yuan for the boss.
3 x 9 = 27 yuan + 2 yuan hidden by the waiter = 29 yuan, this calculation is fundamentally wrong. It would be a mistake to calculate expenses (which no longer exist) and income (which exists) together. This is a conceptual confusion and is more common.
The actual expenditure is 9 yuan per person for 3 people, a total of 27 yuan; The boss and waiter have no expenses, it is income...
Income and expenditure are balanced, 3 * 9 = 2 + 25 (this is a complete transaction), there is 3 yuan without a transaction, or equivalent transfer. It can be expressed as: 3 * 9 + 3 = 2 + 25 + 3
2) Hawker pricing misconduct. Sold in two parts** should be multiplied by 2, green onion white yuan catty, green onion green yuan catty. Otherwise, he should change the unit of measurement.
If you sell it in 3 parts, it must be 3 times, otherwise you will lose more. 4 parts sell **4 times. If the hawker sells onions by the root, there will be no problem.
3) A total of 5 days, the first 4 days 1 meter, the 5th day will be there at once...
4) You can eat 15 of them, and borrowing 1 cent or 1 peach pit can solve the problem.

Anonymous users2024-02-021, because the boss charged 25, so he charged more than 8 yuan per person, not 8 yuan per person, which should be in the final calculation. 2. Since the onion is calculated by catty, no matter how the onion is white and the green onion leaves, the price per catty is unchanged. 3,5 days. 4,14 pcs.
