How to use 3 ml and 5 ml measuring cups to measure 4 ml of water

The first time put a full 5mlPour the measuring cup into a 3 ml measuring cup, do the same for the second time, and then pour the remaining water together twice, and the result is 4 ml of water.

ml is milliliter, unit of measurement.

When the unit of measurement is expressed in letters, in general, the unit symbol letters are lowercase; When the unit ** is used in the name of a person, the first letter of the symbol must be capitalized. Only the volume unit "liter" is special, and this symbol can be written as an uppercase l or a lowercase l. This is because the symbol for "liter" was originally lowercase, due to the lowercase l with Arabic numerals.

1 It is difficult to distinguish, and later the International Conference on Weights and Measures made a resolution that the symbol of "liter" can be written as an uppercase l, so that in the case that lowercase has not been abolished, both upper and lower case are used.

This is the International System of Units.

is the only symbol that is not named after a scientist and can be capitalized. In accordance with the requirements of the International Authority, the letter used to denote milli (10 -3) is "m" and should not be mixed with the letter "m" for mega (10 6).

Hello, is there a scale on the measuring cup? If there is a scale, you can measure it directly with a 5 ml measuring cup.

If there is no scale, it is slightly troublesome: 1. Fill a 5ml measuring cup with water first, and then pour it into an empty 3ml measuring cup, at this time there is 2 ml of water left in the 5ml measuring cup; 2. Pour the remaining 2ml of water in the 5ml measuring cup into the empty 3ml measuring cup, and there is 2ml of water in the 3ml measuring cup; 3. Finally, fill a 5 ml measuring cup with water, fill the 3 ml measuring cup (there is already 2 ml of water in it), and then there will be 4 ml of water left in the 5 ml measuring cup. Hope mine can help you.

First use a 3L cup to hold, then pour in a 5L cup, then fill a 3L cup and pour the 5L cup again until the 5L cup is full, so that there is 1L of water left in the 3L cup, pour the water in the 5L cup, pour the remaining 1L 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.

Similar example: a six-liter container, and a five-liter container, water gives you an infinite amount of water. How to use them to measure out three liters of water.

Only these two containers can be used, and the shape of the container is irregular,)

five litres of water to the fullest;

Pour into a six-liter bucket;

Fill another five liters;

Fill a six-litre bucket with a five-litre bucket so that there are 4 litres left in the five-litre bucket;

Empty a six-litre bucket;

Pour four litres of water into a six-litre bucket;

Fill a five-litre bucket;

Fill a six-liter bucket with a five-litre bucket;

This leaves three liters in a five-liter bucket.

Fill 5 litres first, pour 3 litres, put the remaining 2 litres into the third container, and repeat once to get 4 litres of water.

Measure five litres of water first, pour it into a three-litre cup, and leave two litres left, and once measured, two litres plus two litres equals four litres.

Pour 3 liters first, then pour it into 5 liters, then pour 3 liters, then pour 2 liters into 5 liters, pour 5 liters into light, pour 1 liter from 3 liters into 5 liters, pour 3 liters into 5 liters, and then turn it into 5 liters, and then turn it into 5 liters, and then 5 liters of water in it.

Fill 5 litres and pour into 3 litres empty cup, there are 2 litres left in the 5 litre cup, empty the 3 litre cup, pour 2 litres of water from the 5 litre cup into the 3 litre cup, fill the 5 litre cup again, pour the 3 litre cup to the full, there are only 4 litres of water in the 5 litre cup.

Fill with 5 liters of water.

Use it to pour a full 3 liters.

The rest is 2 liters.

Repeat. There are 4 liters.

There is no measuring cup that can measure 5ml with a flat spoon at home, which is about 5ml. ‍

A teaspoon is also a unit of volume measurement in cooking. The standard for teaspoons varies from country to country, but they are usually around 5 ml. In the United States, federal law stipulates that 1 US teaspoon is equal to 5 ml, and this standard is now used in Australia, Canada, New Zealand and the United Kingdom.

Traditionally, 1 US teaspoon is equivalent to US fluid ounces (milliliters); Traditionally, 1 inch teaspoon is equivalent to an imperial fluid ounce (milliliter). While 1 tablespoon equals 3 teaspoons in most places, 4 teaspoons equals 1 tablespoon in Australia.

One teaspoon = 5; 1 2 teaspoons = ; 1 4 teaspoons =

The purpose of the measuring cup.

Measuring cups are widely used in laboratories of scientific research, colleges and universities, medical and health care, industrial and mining enterprises and other units, for measuring various volumes of liquids. The shape of the glass measuring cup is a round table with a large top and a small bottom, which can hold more liquid than a measuring cylinder.

Relatively speaking, it must be washed before use, dried and flattened, and then the solution must be injected on the scale line slightly higher than the required capacity, and then the excess part is slowly poured out until the lower edge of the meniscus of the solution is just at the edge of the scale line of the required capacity, that is, the required measured capacity. The solution should be poured out of the mouth slowly as it is poured out of the cylinder, and finally the cylinder mouth is in contact with the wall of the bearer to remove the final solution.

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.

Pour 5 ml of a full cup of water, pour the remaining 1 ml into a 10 ml cup 2, repeat step 1 again, 2 ml in a 10 ml cup 3, repeat step 1 at this time, pour 3 ml of water into a 10 ml cup and pour 8 ml into a 10 ml cup at this time.

There is a scale on the measuring cup, and you can measure 2 ml directly.

5ml is about the same capacity as an eye drop bottle, and when compared with an ordinary beverage bottle cap, it is about the same as two bottle caps.

The diameter of a bottle cap of mineral water is about three centimeters, and the height is about one centimeter, so the volume is about seven cubic centimeters, excluding the volume of the bottle cap itself, the liquid contained is about five milliliters.

The milliliter is a unit of measurement for volume, and the symbol is ml (for the abbreviation of milliliter), which is equivalent to cubic centimeter (CC).

The milliliter itself is not an International System of Units (SI) unit, but a non-SI unit that is accepted for use in conjunction with SI, and is not internationally applicable.

Convert to 1 cubic centimeter cubic decimeter.

1 ml liter.

1 ml 1 cubic centimeter.

1 liter = 1000 ml.

1 liter 1000 cubic centimeters = 1 cubic decimeter.

1 μl 1 cubic millimeter.

There is a scale on the measuring cup, and you can measure 2 ml directly.

Here, of course, is a math problem. The method must have a third empty cup (large enough), otherwise it can't be done.

It's simple to have a third empty cup.

Fill 11 cups and pour 7 cups, 3 remaining, pour into the first empty cup. Repeat 3 times to get 9 in the third cup. Pour the third empty cup of water into 7 cups, and the rest is 2.

This question is addition and subtraction. The 3 ml bottle is filled with the 5 ml bottle poured onto it, and after repeating once, 1 ml is left for the 3 ml bottle.

Pour all the water out of the 5 ml bottle and the remaining 1 ml from the 3 ml bottle into the 5 ml bottle. Fill the 3 ml bottle with another 5 ml bottle poured onto the 5 ml bottle.

Minus the formula of the Dharma.

1. Minus - minus = difference.

2. Difference + subtraction = subtraction.

3. Minus - difference = minus.

Subtraction-related properties.

1. Inverse modulus in the exchange rate: subtraction is anti-commutative, if a and b are any two numbers, then.

a-b)=-b-a)

2. Anti-associative law: Subtraction is anti-associative, and when trying to redefine subtraction, then.

a-b-c=a-(b+c）

Fill the 3 ml bottle and pour it to the 5 ml side side line, repeat once to leave 1 ml for the 3 ml bottle. Pour all the water out of the 5 ml bottle, and pour the remaining 1 ml into the 5 ml bottle of the 3 ml bottle. Then fill the 3 ml bottle and pour it into the 5 ml wide booklet.

The 300 ml bottle is filled with a 500 ml bottle, and after repeating once, 100 ml is left for the 300 ml bottle. Pour all the water in the 500 ml bottle and the remaining 100 ml from the 300 ml bottle into the 500 ml bottle. Then fill the 300 ml bottle with the 500 ml bottle.

1. Fill a 5ml cup with water.

2. Pour water from a 5 ml cup into a 3 ml cup until full, leaving 2 (5-3) ml of water in the 5 ml cup.

3. Select the water in the 3ml cup, pour the remaining water in the 5ml cup into the 3ml cup, at this time the 5ml cup is empty, and the 3ml cup is 2ml water.

4. Fill the 5ml cup to the brim and continue to pour water into the 3ml cup until it is full, and 3ml is the full cup.

5. At this time, 4 (5-1) ml of water can be obtained in a 5 ml cup.

Pour into a 3 ml cup, pour 3 ml into a 5 ml fill, pour 3 ml from a 5 ml cup to fill up, pour the remaining 2 ml into a 3 ml cup and 5 ml in a fill.

5 ml filled, poured into a 3 ml cup, 3 ml poured out, after pouring the remaining 2 ml into a 3 ml cup, 5 ml in the fill, poured 3 ml from a 5 ml cup to fill up, 5 ml left 4 ml.

Fill a 5ml glass full of water and pour half of it. Fill up the 3 ml one and pour it out. Just pour the two cups of water together.

The first step is to fill the 30ml and 25ml measuring cups with water.

The second step is to fill 30ml and 25ml of water into a 50ml measuring cup, and the remaining 5ml into a 25ml measuring cup.

The third step is to fill the 30ml measuring cup with a 50ml measuring cup, fill 25ml with 30ml, and then pour the 25ml measuring cup water into the 50ml measuring cup, at this time, the 50ml measuring cup water is 45ml, the 30ml measuring cup is 10ml, and the 25ml is empty.

Step 4: Pour the water from the 30ml measuring cup into the 20ml measuring cup.

The fifth step is to fill the 30ml measuring cup with a 50ml measuring cup, and then fill the 25ml measuring cup with a 30ml measuring cup, at this time the 50ml measuring cup is 15ml, the 30ml measuring cup is 15ml, and the 25ml measuring cup is 25ml

Step 6: Fill 25ml of measuring cup water into a 50ml measuring cup, which is 40ml

How to take out 40 ml of water with 50 ml, 30 ml and 25 ml measuring cups?

Fill a 50 ml measuring cup filled with water into a 30 ml measuring cup, and there are 20 ml left in the 50 ml measuring cup, and repeat it again, isn't it 40 ml.

Because 40 = 30 + 10, 10 = 2 5. So first fill 30 ml and pour it into a 25 ml container, pour the remaining 5 ml into 50 ml, measure it again, there will be 10 ml, and then fill 30 ml and pour it into 50 ml, a total of 40 ml.

Personally, I think so, you can fill a 50ml cup with water and pour it into a 30ml cup. After all the pouring is done, the remaining water is 20 ml. Pour this water into a 25 ml cup and repeat the above behavior to get 40 ml of water.

In that case, you can use 20 ml of water, and 40 ml of water is also possible.
