How to divide 100 ml levels into 70 and 30 vessels

1.Pour 100 ml of water into a 30 ml cup. There are 70 ml left in the original cup.

2.Pour the 30ml water into a 70ml cup.

3.Fill another 30 ml cup and pour into a 70 ml cup. At this time, there are 40 ml left in the original cup, and 60 ml in the 70 ml cup.

4.Fill another 30 ml cup and pour in a 70 ml cup and fill it up. At this time, the original cup has 10 ml left, the 30 ml cup has 20 ml left, and the 70 ml cup is full.

5.Pour all the water in the 70 ml cup into the original cup, and pour all the water in the 30 ml cup into the 70 ml cup. At this time, there were 80 ml in the original cup, the 30 ml cup was empty, and the 70 ml cup had 20 ml.

6.Fill the 30ml cup. At this point, the original cup had 50 ml in it, the 30 ml cup was full, and the 70 ml cup had 20 ml in it.

7.Pour all the water from the 30 ml cup into the 70 ml cup. At this time, the original cup had 50 ml in it, the 30 ml cup was empty, and the 70 ml cup had 50 ml in it.

Pour 70 to the brim, pour 70 to 30 twice, there is still 10 left, change the 10 to the 30 cup, there is 20 space left in the 30 cup, pour the 70 quilt again, and then the 70 cup fills up the 20 space just now, and the rest is 50

100 cups, 70 cups, 30 cups.

Divide according to the above.

Solution: 1. First use a 30ml cup to take 30ml of water and pour it into a 70ml cup.

Then the remaining volume of water = 100-30 = 70 ml, while the remaining volume of a 70 ml cup = 70-30 = 40 ml.

2. Then pour 30ml of water into a 70ml cup with 30ml of water.

Then the remaining volume of water = 70-30 = 40 ml, the remaining volume of the 70 ml cup = 40-30 = 10 ml.

3. Take 30ml of water from a 30ml cup, slowly pour it into a 70ml cup, and fill the 70ml cup.

Then the volume of water remaining in the 30 ml cup = 30 - (40-30) = 20 ml.

4. Then pour all the water in the 70 ml cup into the original water container, then pour 20 ml of water in the 30 ml cup into the 70 ml cup, and finally pour 30 ml of water into the 70 ml cup with the 30 ml cup, then the volume of water in the 70 ml cup = 20 + 30 = 50 ml.

The volume of water in the original container = 100-50 = 50 ml.

According to the above operation, you can divide 100 ml of water into two equal parts with an empty 30 ml and a 70 ml cup.

100ml is actually a du with a bai cup

Let's do it. First to 30ml, transfer to zhi70ml cup, again, it is 60ml. Edition is left with 40 ml and pours.

Right 30ml cup, then 70ml cup now has 60ml, use 30 cups to go in 10ml slowly, there is 20ml left, then clean 20, pour full 30, add up.

ml into a 70 ml cup. Pour 30 cups into cups.

Pour the cup into 100.

Pour 30 in a cup, at this time 70 cups with 10 ml.

5. Pour another 10ml of water into 30 cups.

6. At this time, there are only 90 ml in 100, and after pouring into 70, 20 ml is left in 100.

7. Pour 30 into 100, plus the original 20 ml, for 50 ml.

Unit Conversion. 1l = 1000ml 1000ml = 1000 cubic centimeters = 1 cubic decimeter 1 ml = 1 sissi (cc).

1 ml of liquid water = 1 cubic centimeter of liquid water.

1 ml of liquid water weighs 1 gram at 4 degrees Celsius.

1 ml = 1 cubic centimeter.

Start by filling a 500 ml container three times to get 1500 ml of water. Pack into a large container.

Then use a 700ml container to remove two 700ml from this 1500ml of water.

In this way, exactly 100 ml of water is left in the large container.

If the container doesn't have an intermediate scale, then do it in two steps!

First, fill the 700 ml container with water and pour the 500 ml container to the brim.

200 ml of water is obtained in a 700 ml container.

Second, I pour out a 500 ml container and divide 200 ml horizontally, and it's OK!

Take 700 ml of water and put it in a 500 ml container, the remaining water in the 700 ml container is 700-500 = 200 ml, pour the 200 ml of water into a 500 ml container;

Take 700 ml of water and fill the 500 ml container, leaving 700-(500-200) = 400 ml in the 700 ml container, and then pour it into the empty 500 ml container;

Take 700 ml of water and fill up the 500 ml container, leaving 700 - (500-400) = 600 ml in the 700 ml container.

The 600 ml of water is poured into a 500 ml container, and the amount of water in the 700 ml container is 600-500 = 100 ml.

You know what to do. Adopt it!

Fill 700 ml, pour out 500 ml and remain.

200 ml, then pour out half of it, that is.

100 ml.

Fill a 500ml container with water, pour a 700ml container, fill a 500ml container with water and then fill a 700ml container until it is full, pour out the water from the 700ml container, continue to add water, add water to the 700ml container for the third time until it is full, and the remaining water in the 500ml container is 100ml.

Use a 700 ml container, fill 700 ml, pour 500 ml, leave 200 ml, pour 500 ml, pour 200 ml. The second time it is filled with 700 ml, unlucky 500 ml, remaining 400 ml, poured 500 ml and poured 400 ml. The third time fill 700 ml, pour 500 ml, leave 600 ml, pour 500 ml, pour 500 ml again, 100 ml remaining, at this point it is the measured 100 ml.

Step 1: 700-500=200

Put 200 ml of water in a 500 ml container.

Step 2: Take 700ml of water and pour it into a 500ml container to fill up with 300ml and leave 400ml left.

Pour out the water in the 500ml container and put the 400ml of water in the 500ml container.

Step 3: Take 700ml of water and pour it into a 500ml container to fill up with 100ml and leave 600ml left.

Pour out the water in the 500ml container, pour out the remaining 600ml of water in the 700ml container and pour out 500ml, and the rest is 100ml of water.

Fill the 500ml container with water and pour it into the 700ml container, at this time the 700ml container will contain 500ml of water.

Fill the 500 ml container with water again, then pour the 700 ml container until the 700 ml container is full of water, at which point the 500 ml container has 300 ml of water inside.

Then pour the water from the 700ml container, then pour the water from the 500ml container into the 700ml container, and then the 700ml container has 300ml of water.

Then fill the 500 ml container with water, then pour it into the 700 ml container until the 700 ml container is full of water, at this point, the 500 ml container has 100 ml of water.

Finally, the water in the 700ml container is emptied, leaving only 100ml of water in the 500ml container.

Fill the 700 ml container with water and pour it into the 500 ml container, the remaining 200 ml, the remaining 200 ml with your eyes, half is 100 ml.

Another way is to repeat the measurement several times, that is, pour the remaining 200 ml into the small container and put it elsewhere for later use, fill the 700 ml container three times, each time the remaining 200 ml, three times is 600 ml, and finally pour 600 ml of water into the 500 ml container and the remaining 100 ml.

1.Fill the 700 ml container with water and pour into the 500 ml container, leaving 200 ml 2Empty another 500ml of water.

3.Pour half of the 200 ml of water into a 500 ml container4Both containers are filled with 100 ml of water.

500 ml into the 700 ml container once, pour it again, 300 ml is left in the 500 ml container, pour the 700 ml out, pour the remaining 300 ml in the 500 ml into the 700 ml container, after one more pouring, there is 100 ml left in the 500 ml container.

Mathematical process, 3 500 = 1500 2 700 = 1400

Add water to the 500ml container three times, pour water twice into the 700ml container to fill the glass, and the remaining water is 100ml.

Fill 700 first, then pour 500 li to fill up, and put the remaining 200 into another container, so that you get 600 ml three times, then pour 500 and pour it full, and the rest is 100 ml.

700 containers are empty, 500 containers are full and poured to 700 containers and 500 containers are filled again, poured until 700 containers are full, 500 containers are left with 300700 containers are poured, 300 containers of 500 containers are poured into 700 containers and 500 containers are refilled, and when 700 containers are full, then 500 containers are left with 100 to solve.

Fill up with 700 and pour 500, 7 with 200 left, 5 poured out, 200 into 5, 7 filled with 5, 7 with 400 left in 7, pour out 5 with water and pour 400 into 5, then fill 7 with 5, 600 in 7 at this time, pour 5 out with 600 and fill 5 with 600, then 7 will have 100 ml left.

This one is simple:

The 500ml container is filled and poured into the empty 700ml, the 700ml has 200ml left, then the 500ml is filled and the 200ml is filled, there is 300ml left in the 500ml, the 700ml that is already full is poured out, the remaining 300ml is poured into the 700ml container, there is 400ml left in the container, then the 500ml container is filled with water and the 400ml free capacity is filled, and there is 100ml of water left in the 500ml container!

The measuring cups of 500 ml and 700 ml are C5 and C7 respectively.

The steps are: C7 full, pour C5 full, C7 left 200 ml, C5 empty, C7 200 ml poured into C5, C7 full, pour full C5, C7 left 400, C5 empty, C7 pour C5, C5 left 400 ml, C7 full, pour C5, C7 left 600 ml, C5 empty, C7 full C5, C7 left 100 ml.

Finally, 100 ml is left in C7. FYI!

Step 1: Fill the 700ml container with water, pour the water into the 500ml container and fill it with 200ml of water remaining in the 700ml container.

Step 2: Empty the 500ml container and pour the remaining 200ml of water into the 500ml container.

Step 3: Fill the 700ml container with water again, then pour the water into the 500ml container, leaving 400ml of water at this point. Empty the 700ml container after marking the water level at the height of the water.

Step 4: Pour the water from the 500ml container into the 700ml container and raise the liquid level to the mark. At this point, the water in a 500 ml container is 100 ml.

Let's say cup 1 is 700 ml and cup 2 is 500 ml.

1 pour into 2....Number 1 is 200

Pour No. 1 200 into No. 2 and top No. 1 again.

Pour from No. 1 to No. 2 300, No. 1 remaining 400, then pour No. 1's 400 into No. 2, pour No. 1 from No. 700 into No. 2 100, No. 1 remaining 600, No. 2 is 500 and pour from No. 1 remaining 600 into No. 2 500, and there is 100 left. If you don't know, you can ask again.

Fill the 700ml container in two 500ml containers, leaving 400ml of water in the 500ml container. Empty the 700ml container, pour 300ml of water from the 500ml container into the 700ml container, and fill the 700ml container with a full 500ml container, then the remaining water in the 500ml container is 100ml.

First, fill the 500 ml container with water and pour it into the 700 ml container; Then fill the 500ml container with water, then pour it into the 700ml container, when the 700ml container is filled with water, there is 300ml left in the 500ml; Pour out the filled 700ml. Pour the remaining 500ml into the 700ml container, fill the 500ml and continue to pour the 700ml container, when the 700ml container is full, there is exactly 100ml of water left in the 500ml container.
