3 liter cups, 5 liter cups, 1 How about

Fill the 5 litre cup first, then pour the water into the empty 3 litre cup until it is full, then pour the water out of the 3 litre cup, then pour the remaining 2 litres of water from the 5 litre cup into the empty 3 litre cup, then the 3 litre cup now has 2 litres of water, now fill the 5 litre cup again, pour it into the 3 litre cup until it is full, then pour 1 litre out of the 5 litre cup to fill the 3 litre cup, now there is 4 litres of water in the 5 litre cup.

The 5 liter cup is full, pour 3 of them into the 3 liter cup, just full, then the 5 liter cup has 2 liters left, pour these 2 liters into the 3 liter cup, then fill the 5 liter cup with water and pour 1 liter of water into the 3 liter cup, at this time, the 3 liter cup is full, and the 5 liter cup is 4 liters of water.

A five-liter cup is filled with water, and half of a three-liter cup is poured into it, so that a five-liter cup is a liter of water. Fill the three-liter cup with water and pour half of the five-liter cup so that the five-liter cup is literal.

1. Fill the 5-liter cup and pour into the 3-liter cup until full.

At this time, there are 2 liters of water left in the 5-liter cup.

2. Pour out the 3 liters of water in the cup and pour the remaining 2 liters of water in the 5 liters cup into the 3 liters empty cup.

At this time, there are 2 liters of water in a 3-liter cup.

3. Fill the 5-liter cup, and then use the 5-liter cup to fill the 3-liter cup that was not full.

At this time, the remaining water in the 5-liter cup is 4 liters.

Fill a 5-liter cup with water and pour it into a 3-liter cup, and when the 3-liter cup is full, the remaining water in the 5-liter cup is exactly 2 liters.

Pour out the water in the 3 liter cup, pour the 2 liters of water you just got into the 3 liter cup, and fill the 5 liter cup with water, so that there are a total of 7 liters of water in the two cups (2 liters for a cup and 55 liters for a glass).

Pour the water from the 5 litre cup into the 3 litre cup, and when the 3 litre cup is full, the remaining water in the 5 litre cup is exactly 4 litres.

Addition Rule: When using the "truncation method" in addition or subtraction, add or subtract directly from the left high position (while paying attention to whether the next digit needs to be carried and misplaced) until you get the answer that the option requires precision. When using the "truncation method" in multiplication or division, in order to make the results as accurate as possible, it is necessary to pay attention to the direction of the interception approximation:

1. To expand (or shrink) one multiplier factor, it is necessary to shrink (or expand) another multiplier factor.

2. To expand (or shrink) the dividend, it is necessary to expand (or shrink) the divisor. If you are looking for the sum or difference of the two products (i.e., a*b+ -c*d).

3. If one side of the plus sign is enlarged (or reduced), the other side of the plus sign needs to be narrowed (or expanded).

4. Enlarge (or reduce) one side of the minus sign, then enlarge (or reduce) the other side of the minus sign.

Fill a 3-litre cup with water and pour it into a 5-litre cup, fill a 3-litre cup with water again and pour a 5-litre cup with water, leaving 1 litre of water in a 3-litre cup; Vacate the 5-liter cup, pour in the remaining 1-liter water, fill the 3-liter cup with water and pour it into the 5-liter cup and you're OK!

Hope it helps.

Five litres are filled, three litres are poured, two litres remaining, the three-litre cup is poured out, the five-litre cup with two litres of water is poured into the three-litre empty cup, two litres of water are poured into the three-litre cup, the five-litre cup is full, and then the three-litre cup (containing two litres, poured into one litre) is filled with a five-litre cup to get four litres.

For example: first use a 3L cup to hold, then pour in a 5L cup, then fill a 3L cup and pour it into a 5L cup again until the 5L cup is full, so that there is 1L of water left in the 3L cup, pour the water from the 5L cup, pour the remaining 1L of water from the 3L cup into the 5L cup, and then fill the 3L cup with 3L water and pour it into the 5L cup, so that there is 4L of water in the 5L cup.

liters, volumetric units.

The liter is expressed as l in the International System of Units and the sub-unit is the milliliter (ml). The conversion relationship between liters and other volume units is:

1 cubic meter = 1000 liters.

Pour water into the 3-liter cup in the 5-litre cup, there are 2 litres left, the 3-litre cup is empty, pour the remaining 2-litre water, the 3-litre cup is still 1 litre free, the 5-litre cup is full, and then pour the water into the 3-litre cup until it is full, and the 5-litre cup has 4 litres of water left.

Fill the five-liter cup and fill the three-liter cup with two liters left.

Empty the three-liter cup and pour the remaining five-liter cup into the three-liter cup, and the three-liter cup will be full with one liter left.

Now fill the five-liter cup and pour water into the three-liter cup until the three-liter cup is full, and the rest of the five-liter cup is four liters.

Step 1: Fill a five-liter cup and pour into a three-liter cup. There are also two liters of water in a five-liter cup.

Step 2: Pour out the water in the three-liter cup and pour two liters of water from the five-liter cup into the three-liter cup. The three-liter cup is still one liter short of water and it is full.

Step 3: Fill the five-liter cup and pour the water in the five-liter cup into the three-liter cup, and there will be four liters of water left in the five-liter cup.

kettle, its height should be in 20cm. The diameter is 10cm.

Such a kettle can be used by everyone. The mineral water we usually drink is 500ml, which can hold two bottles of mineral water in it. We also see an enlarged mineral water, presumably.

A kettle about the size of this ridge, it was just right for us to take it out. He's about the same length as our shoes.

Basic definition: liter, volumetric unit.

liters in the International System of Units.

is expressed as L, and the unit of the secondary base level is milliliter (ml). The conversion relationship between liters and other volume units is:

1l = 1000ml = cubic meter 1 cubic decimeter 1000 cubic centimeter.

1l=1dm*1dm*1dm=10cm*10cm*10cm。

1ml = 1 cubic centimeter 1cc.

1 cubic meter = 1000 liters.
