Two bags of rice weigh the same, the first bag uses 1 3, the second bag uses 1 3 kg, and the rest we

Three cases: One: Two bags of rice weigh the same and both are less than 1 kilogram, (let's say kilograms).

Well, it's the weight of the first bag that remains.

Because: the first bag uses 1 3, and the 1 3 of the kilogram is the kilogram, and the remaining kilogram; And the second bag also uses 1 3 kilograms, leaving kilograms, kilograms kilograms.

So, the weight left over from the first bag.

Second, the two bags of rice are equally heavy, both of which are exactly 1 kilogram.

Well, the rest is just as heavy.

Because: the first bag uses 1 3, 1 3 of 1 kg is 1 3 kg, and the second bag also uses 1 3 kg, and it uses just as much;

So, the rest is equally heavy.

3. Two bags of rice weigh the same weight, both more than 1 kilogram (assuming kilograms).

Well, the weight of the rest of the second bag.

Because: the first bag uses 1 3, and the 1 3 of the kilogram is the kilogram, and the remaining kilogram; And the second bag uses 1 3 kg, the remaining kg, 1 kg kg.

So, the weight left over from the second bag.

It's different. Suppose that both bags of rice weigh 3kg, then use one-third to use 1kg, and leave 2kg to use one-third of the kilogram and eight-thirds of the kilogram to rise. So it's not as heavy.

Up in the air. The second generation uses 1 3 kilograms, indicating that the second bag may be 1 kilogram or tens of thousands of tons. It may also be other heavy.

If it's 1 kg, it's the same weight as the first generation, and if it's not, it's not the same weight.

Not necessarily, depending on the original mass, if the original weight is greater than one kilogram, the first bag weighs, etc., the same as the second bag.

According to the title: the first bag of rice = the second bag of rice.

The first bag of rice - 9 kg ......（1）

2nd generation rice - 14 kg ......（2）

1) - (2) = 1st bag of rice - 9 - 2nd bag of rice + 14 = 5 kg.

A: Now the first bag of rice is a bit heavier, 5 kg heavier than the other.

Because the first bag has rice (a-9) kg, the second bag has rice (a-14) kg, (a-9) - (a-14).

a-a+14-9

5 (kg) So, now the first bag is a bit heavier, 5 kg heavier than the second bag.

The first bag weighs 14 9 5 kg heavier than the second.

If there are two bags of rice weighing the same weight, the first bag uses nine kilograms and the second bag uses 14 kilograms, then the first bag should be heavier, and the first bag is five kilograms heavier than the second bag.

There were 2 bags of rice of the same weight, the first bag used 9 kg and the second bag used 14 kg, and now the first bag is heavier, 5 kg heavier than the other.

There are 2 bags of rice of the same weight, the first bag uses 9 kg, the second bag uses 14 kg, and now that bag is heavier? How many kilograms is heavier than another bag?

Because 14 kg >> 9 kg.

So the first bag weighs and is 14-9=5 (kg) heavier than the second bag

Because the first bag - 9 kg = the second bag - 14 kg, it can be seen that the second bag - the first bag = 14-9 = 5, that is, the second bag weighs 5 kg.

The second bag of rice weighs.

36 kg.

Weighs 36 kg.

The second bag of rice is 1 5 lighter than the first bag, so the weight of the second bag of rice is 45 (1-1 5) = 45 4 5 = 36 kg.

The second bag of rice weighed 36 kg.

Take out 3 4 kg from the second bag and put it into the first bag. The weight of the bag is:

25+3 4 = 25 faction 3 4

And the weight of the two bags is the same, and the two bags weigh together:

25 3 4) x 2 = 51 1 2 kg.

If you can use the answer, please "" which line of the answer is.

Shirt is a land kilogram).

A: These two bags of rice weigh a total of kilograms.

The first land rotten bag weighs 25 kg, and 3 4 kg is taken out from the second bag of Hesheng and put into the first bag, at this time the first bag weighs kg (3 4 kg = kg). The two bags of rice are also heavy, with a total weight: kilograms;

A: The two bags of rice weigh a total of kilograms;

25+3 4) 2 = kilogram (51 and 1/2 kilogram).

Answer: The total weight of the two bags of rice in the cave is kilograms (51 and 2 parts of the suspect is 1 kilogram).

2 (25 + 3 4) = kilograms

These two bags of rice are missing a total of megawatts of kilovolt rental rows

kilogram) kilogram) Answer: These two silver loss rocks are made of bag Feng jujube god rice weighing a total of kilograms.

The second bag of rice weighs = 25 + 2 3 limb wheels 4 = kg).

These two bags of tomato rice weighed a total of = 25+ kg).

25+3 4 kg.

The second bag of rice is a thousand cartons.

The two bags of rice in Zaozhou weighed a total of 25+ kilograms.

This question raiders can do this:

25 + 3 4 = 25 and 3 4

25 and 3 4 2 = 50 and 6 4

Kilogram bends.

Two bags of rice are missing sample weight, take out 1 2 from the first bag, and take out 1 2kg from the second bag. The rest of the rice is as heavy. How much is the Zheng belt for each of the two bags of rice?

Solution: Let these two bags of rice be argued as x and y kilograms, x=yx-1 2x=y-1 2

1/2x=y-1/2

Substituting (1) formula:

1/2x=x-1/2

1/2x=1/2.

x = A: Both bags of rice weigh 1 kg.

This can be solved by listing a two-dimensional system of equations, assuming that two bags of rice are divided into x and y, and the system of equations is listed according to the meaning of the question

y－x=15…Jeong-hui....①

x×1/3=y×2/7……②

Multiply both sides by 3 at the same time to get :

x=y×6/7=6/7y……③

Put substitution into it:

y－6/7y=15

1/7y=15

y=105……④

Put substitution into it:

105－x=15

x=90 so x=90 and y=105

Answer: The two bags of rice are 90 kg and 105 kg respectively.

Let the original weight of the rice be a kilogram, then:

The first bag remains: (1-1.)

a = 2a kg; The second bag was left: A-1

kilograms, when a 1, 2

a a-1 weight remaining in the second bag;

When a=1, 2

a=a-13, the weight of the remaining rice in the two bags is equal;

When a=1, 2

a a-13, the weight of the rest of the first bag

Therefore, d is not sure

It should be the second bag weight.

For the first third of the bag is equivalent to dividing one part into three parts, and taking one of them;

And the second bag uses a third of the kilogram, and the third kilogram is less than a kilogram, then the rest must be heavier than the second bag.

So the rest of the first bag is heavier.

If the first bag weighs x,,, then the second bag weighs x+15

From the meaning of the title, we can get 1 3x=2 7(x+15).

1/3x=2/7x+30/7

1/21x=30/7

x=90

Solution: If the first bag of rice weighs x kg, then the second bag weighs (x + 15) kg.

1/3x=2/7（x+15）

1/3x=2/7x+30/7

1/21x=30/7

x=90A: The first bag of rice weighs 90 kg.

Set: The first bag of rice weighs x kg, the second bag of rice weighs y kg, and the inscription knows 1 3x=2 7y

y-x=15

Solution: x = 90 kg, y = 105 kg.

A: ......

Let the first bag of rice weigh x and the second bag weigh y

y=x+15

1/3x=2/7y

The solution yields x=90 and y=105
