9 oranges are light, and can you divide it with a balance twice

Yes, divide the oranges into three groups, 3 in each group, and put two groups on both sides of the scale for the first time, if they are the same weight, then the target oranges are in the group that has not been weighed; Otherwise, in the lighter group. This determines the group of target oranges.

The second time, take two oranges in the group with the target orange and place them on either side of the scale, the principle is the same, if it is the same weight, the other is the target orange, and vice versa, the light one.

Divide the oranges into thirds, three each.

1.Weigh the first and second servings.

If the balance is balanced, the lighter one is in the third part.

If it is unbalanced, the lighter one is on the back side of the scale.

2.Choose two of the light oranges and place them on either side of the scale.

If the balance is balanced, the third is a light orange.

If it is unbalanced, the light one is on the back side of the balance trend.

Yes, divide it into 3 equal parts, 3 oranges each, put each of the 3 parts on each side of the scale, if you want to balance it, the lighter one is among the remaining 3 oranges, you can divide it into 3 more parts, each part is 1, 1, 1, 1, and so on.

Again, if it is weighed according to the imbalance, it can still be weighed twice.

Do you know what to do, tell you that there is a math book, you look for it carefully.

Actually, I would too. It's just late, and the first few will -=-=-=-=-=-=

Put 7 bags on both sides of the scale, if the balance is balanced, then the light weight is the remaining bag.

If it is not flat, take the light side, and then weigh the second time, three bags on each side, if balanced, the light quality is the remaining bag, if it is not balanced, and then take the light side, called the third time...

So I can definitely find out the light bag after weighing it three times.

The nine bowls are divided into three groups of A, B, and C, each with three in each group.

Choose two groups A and B, if it is the same weight, the light bowl is in C, and if it is not the same weight, the light group has a light bowl.

The light group is singled out, choose any two scales, the same heavy is the light one, and the one that is not the same heavy is the light one.

Summer homework, right?

The first time, put 3 bowls on both sides of the scale, if it is flat, it means that the special bowl is in the remaining three, and then weigh the second time, if it is flat, then it is the last bowl.

If the first time, one side is lighter, then it is one of the three light, and then it is called the second time, understand?

A bottle of orange flour requires 16 grams of orange powder and 9 grams of sugar cubes per cup, and about a kilogram of sugar cubes are needed to complete this bottle of orange powder.

According to the title. Let's say the bottled orange powder is 1 kg.

The calculation process is as follows:

Kilograms of sugar cubes are required

1000x（1/16）×9x（1/1000）=（1/16）x9

kilograms).

First of all, the total weight of orange powder is 450 grams, and each cup is 16 grams, so after brewing this bottle of orange powder, it is 450 16, which is equal to, about 28 times, and each time you need 9 grams of sugar cubes, which is multiplied by 9, then it is grams.

Column: 450 16

According to the title, the calculation is as follows:

g) so about the gram of sugar cubes is needed.

It depends on how much a bottle of orange powder weighs, in fact, you just need to make it in a ratio of 16:9.

Dividing 450 by 16 equals that it takes about 28 times to make a full bottle.

28 times 9 equals 252, which is about 252 grams of sugar.

252 divided by 1000 equals kilograms.

30 + 30 = 60 grams Two oranges = 60 grams Four oranges 30 4 = 120 grams 120 grams - 60 = 60 Two apples - one apple = one apple. One apple = 60

Set: one apple x gram.

30×2+2x=30×4+x

x = 60 so 60 grams for an apple.

50000 10000 = 5, 8 months = 31 days, tons), tons), tons) is right, vidonia is wrong!

1. Orange powder 16 9 1000 = kilograms of sugar cubes are required.

2. Tons) A: In August, this forest can absorb a total of 126 tons of carbon dioxide.

According to the title, the calculation is as follows:

g) so about the gram of sugar cubes is needed.

You should first make sure that you take a different orange and whether it is heavier or lighter than the others. to be able to weigh him out three times.

For example, the orange is known to be heavy.

The first time put six on one side, it must be unbalanced, take out the heavy six and continue to weigh;

The second time, put three on one side, it must be unbalanced, take out the heavy three and continue to weigh;

The third time take out two of them at random and put them on the scale, one on each side, if it is not balanced, the heavier one is the orange to be found; If the scales are balanced, the one that is not put on the scale is the orange that is to be found.

Which one is heavier or lighter than the other 11?
