There is a bunch of grapes, counting from the top to the bottom is 9, counting from the bottom to th

Although I still feel that this question is a bit loophole, after all, there is no way to explain the number, but I think that the vertical number is not too practical, so I just use the number of vertical views to solve this problem, that is, to look at the grapes vertically to count, just like the way to look at the top and bottom of this bunch of grapes.

Solution: I think it's 15, 12-9 = 3 Derive 3 grapes that you don't see from below but see from above.

12 + 3 = 15 Add the error of the two times to the number of grapes seen below.

The grapes are inverted cone-shaped, and the area seen from below will be larger than the area seen from above, although there will be more from below than from above. In other words, there will be an error between looking at the number from above and looking at the number from the bottom, and the difference is the key to solving the problem. There are grapes that can be seen from the top and bottom, and some of the grapes cannot be seen, and this problem exists from both the top and the bottom.

Use a more 12 and subtract a less 9 to get the error on both sides, which is 3. Personally, I think it should be added to 12, because there are many from the bottom up, so there will be at least 12. The 3 that come out of the error from 12 is the final number of grapes.

Waiting for LZ to announce the answer, I don't know if I did it right.

There are 12 large ones at the top and small ones at the bottom, and there are only 9 of them when you can see them all from below.

If you use the calculation, it should be 20, but can the grapes be counted like that?!

If you take a homonym"Clean"It means that it is taken naked. The answer goes without saying!

16 bunches of grapes.

According to the title, Ning Ning picked 9 bunches of grapes and searched Zheng He, there were 7 bunches on the grape trellis, and there were 7 bunches left on the grape trellis bush and 9 bunches were picked off.

There are about 1056 or so.

Usually 70%-80% of a grape is 75% water per megaliter, and about 7% of the remaining 7% of the old material is dissolved in the juice, while everything else is lost during the production process. This means that about 75% + 7% = 82% of the ingredients that can be used in a grape can be used. In the process of fermentation and maturation, about 5% of the grape juice is lost, and only 77% of the wine is actually used, and a wine grape weighs about a gram, and only one gram can be used.

A 750ml bottle of wine weighs about 1,200 grams, and after removing the bottle, the remaining part weighs about 750 grams, which means that the 750 grams are converted from grape juice.

There are 32 bunches of grapes on the trellis, which are ripe, and 9 bunches of 20 bunches have been picked, so how many are left?

The calculation process is as follows, 32-9=23

So there are still 23 bunches of grapes left on the trellis.

In total, there are 32-9 equal to 23 strings.

If you ask how many kinds of strings are left after maturity, then 20-9 equals 11 strings.

32-9 = 23 strings.

There are also 23 bunches of grapes on the trellis.

The least common multiple of 20 and 8 is 40

A: There are at least 40 grapes in this box.

Solution: It is to find the least common multiple of 8 and 20, and find 40 boxes, at least 40 boxes.

There are at least 40 grapes in this box.

Pick 5 9 oh.

5 9 means five bunches of grapes, nine in each bunch.

If the first pile has x pcs, then the second pile will contain 2x-1, the third will contain 2x+2, and the fourth will have 4x

x+2x-1+2x+2+4x=19

9x=18x=2

2x-1=3

2x+2=6

4x=8Answer: The four piles are 2, 3, 6, and 8.

Note: The question is "How to move" not "How to divide evenly" the grapes in order to make two piles of grapes as much, so you can do this:

1.Remove 5 out of 10, both piles are 5, the same amount;

2.Remove 6 out of 10, remove 1 out of 5, and both piles are 4, as much;

3.Remove 4 out of 10 and put one of them into the original 5, and both piles are 6, as much;

One: (10+5) 2=) pcs).

2: (10-5) 2=pcs).

Three: Solution: When the two teams are the same, there are x respectively.

2x=5+10

2x=15x=
