Pour me 4 liters of water, 4 liters of water is a few bottles of mineral water

It should be like this: fill a 5-liter bucket with water, pour water into a 3-liter bucket and fill it up, there are still 2 liters of water in the 5-liter bucket, pour out the water in the 3-liter bucket, pour the remaining 2 liters of water into the 5-liter bucket, there are 2 liters of water in the 3-liter bucket, fill the 5-liter bucket, pour the water into the 3-liter bucket, and now there are 4 liters of water in the 5-liter bucket.

Step 1: Fill a 3L bucket with water and pour the water into a 5L bucket.

Step 2: Fill the empty 3L bucket with water and pour water into the 5L bucket until it is full.

At this point, there is 1 liter of water left in 3 liters because 3 + (5-3) = 5.

Step 3: Pour out all 5 litres of water and pour the water in the 3 litre bucket into it, which means pouring in 1 litre.

Step 4: Fill up another 3 liters of water, pour it into a 5-liter bucket, and you're done.

Hehe. If you think about it carefully, it's very simple.

1. Fill a 5L bucket first. Pour into a 3-liter bucket to fill up. This leaves 2 litres in a 5-litre drum.

2. Pour out the water that you just introduced into the 3L bucket, and pour 2L of the 5L bucket into the 3L bucket.

3. In this way, there are 2 liters of water in a 3-liter bucket, right? It can also hold 1 liter.

4. The last step. Fill another 5-litre bucket. Pour into a 2-liter bucket and fill up. Illustrate. In this step, one liter is poured out of a 5-liter bucket, right? 5-1=4。

It's four liters. Hee-hee.

Fill the 5 litre bucket with a tap and pour the water into the 3 litre bucket, when there is 2 litres of water left in the 5 litre bucket, empty the 3 litre bucket and pour the 2 litres of water into the 3 litre bucket. Fill the 5-litre bucket with water and pour it into a 3-litre bucket (the bucket still has a 1-litre capacity) and when it is full, there will be 4 litres of water left in the 5-litre bucket.

Fill a 5-litre bucket with water, then pour the water into a 3-litre bucket and leave 2 litres of water. Make a marker line on the water level. Then pour out the water in the 3L bucket and pour 2L of water from the 5L bucket into the 3L bucket.

Next, use 5 symbiotic buckets to catch the water until the water surface reaches the marked line, which is the 2 water supply. Pour 2 litres of water from the 3 litre bucket back into the 5 litre bucket to get 4 litres of water.

1。Fill the 5-litre bucket first. Pour into a 3-liter bucket to fill up.

There are 2 litres left in the liter bucket. Pour out the water that you just poured into the 3 liter bucket and pour the 2 liters of water from the 5 liter bucket into the 3 liter bucket.

The liter bucket contains 2 liters of water, and it can hold 1 liter.

4。Fill a 5-litre bucket. Pour into a 2-liter bucket and fill up. This leaves only four litres of water in a five-litre bucket.

I read this question in the teenager Bao Qingtian.

Fill the 5 litre bucket with water, pour the water into the 3 litre bucket and fill it up, there is still 2 litres of water in the 5 litre bucket, pour out the water in the 3 litre bucket, pour the remaining 2 litres of water in the 5 litre bucket, there is 2 litres of water in the 3 litre bucket, fill the 5 litre bucket and fill the 3 litre bucket with water, now there is 4 litres of water in the 5 litre bucket.

No one should answer this question

First fill it with 5L of water, until it enters the 3L cup, 2L of water is left, pour out the water in the 3L cup, and then pour the 2L into the 3L cup, so that the difference between the 3L cup is 1L full, and then fill the 5L cup with water, pour 1L of water into the 3L cup, and there is 4L left.

Measure three liters in a three-liter cup and put it into a five-liter cup, then measure three liters and pour it into a five-liter cup until it is full of Lele, and there is one liter left in the three-liter cup, pour the water from the three-liter cup into the five-liter cup, and then use the three-liter cup to measure the three-liter cup and pour it into the five-liter cup to get four liters of water

5 liters filled with a bottle of water pour into 3 liters, leaving 2 liters.

Empty the 3-liter bottle and pour the remaining 2 liters from the 5-liter bottle.

Fill another 5 litre bottle and pour 1 litre of water into a 3 litre bottle already filled with 2 litres of water.

There are 4 liters of water left in the last 5 liter bottle.

Yes. First fill the 3L bottle with water, pour it into the 5L bottle, then fill the 3L bottle with water, pour the 3L bottle with water into the 5L bottle, at this time there is still 1L of water in the 3L bottle, pour out the 5L bottle of water, put the water in the 3L bottle with 1L of water into the 5L bottle, then fill the 3L bottle with water, pour it into the 5L bottle.

Leave a comment. Bewa recommends: Drinking water is water that meets the sanitary standards of drinking water as raw material, processed by filtration, sterilization and other processes, and can be directly drunk in a closed container. Consumers should pay attention to the following issues when buying bottled drinking water:

1.Try to buy brand products with a certain reputation produced by large-scale production enterprises, and the quality of their products is the best.

2.Pay attention to the product label. Carefully check whether the product name, net content, manufacturer's name, address, production date, shelf life and other contents on the label are standardized.

When drinking natural mineral water, special attention should be paid to checking whether the name of the mineral water source and the approval number that has passed the national (provincial) appraisal and recognition, the characteristic limit index and PH value, the content range of total dissolved solids, main cations (K+, Na+, Ca2+, Mg2+) and anions (HC3-, SO42-, Cl-).

3.See what the bottle looks like. The drinking water packaging bottle should be made of materials that meet the requirements of national standards, and the bottle body should be smooth and clear, with high transparency and good texture.

At the same time, squeeze the plastic bottle body by hand to check whether the cap is well sealed. If there is water oozing from the mouth of the bottle, the cap is not tightly sealed and the drinking water may be contaminated.

4.Pay attention to the organoleptic quality of drinking water. Qualified drinking water should generally be colorless, transparent, clear, odorless, odorless, and not visible to the naked eye.

Drinking natural mineral water allows very small amounts of natural mineral salts to precipitate, but no other foreign substances. Products with different colors, odors, turbidity, flocculents or impurities should not be consumed.

5.Once bottled drinking water is opened, it should be consumed as soon as possible in the short term.

Can you read it? This means filling a 3-liter bottle with water twice, pouring it into a 5-liter bottle, dropping 1 liter into a 3-liter bottle, pouring out the water in the 5-liter bottle, introducing 1 liter from the 3-liter bottle into the 5-bottle, and then filling it with 3 bottles and pouring 5 bottles, exactly 4 liters.

That is, there are two empty bottles, one large and one small, with a known capacity of 5 liters and 3 liters respectively, and it is possible to use these two bottles to obtain water with a capacity of 4 liters.

A: Yes. First fill the large bottle to 5 liters, pour the water in it into the small bottle, so that there are 2 liters of water in the large bottle, pour out the water in the small bottle, and pour the water from the large bottle into the small bottle.

Currently, the large bottle is empty, and the small bottle contains 2 liters of water.

Then fill the large bottle with water, that is, there is 5 liters of water, and fill the small bottle with the large bottle of water. Because the remaining capacity of the vial is one liter, 4 liters of water are obtained.
