So how many grains of rice are there in 100 million grains? Is it so much a handbag? Or is it as much as a sack? The student wondered and shook his head. Some say this, some say that, but there are different opinions, but there is no result.

At this time, the student stood up and said that 100 million grains of rice are as much as 10,000 cups. "It's amazing! But how much is 10,000 cups? ”

How much is 10,000 cups? "The student has no imagination other than to feel a lot. I can't imagine either.

To further appreciate how much of this 100 million grains of rice there is, we continued the test and first weighed 1 kilogram of rice on a scale. Imitate the dress with disposable cups and stumble upon almost 5 cups, which is an exciting number. This means that 1 kilogram of rice is 50,000 grains, and by calculating that 2 kilograms is 100,000 grains, and the number of 100 million grains is 1,000 times that of 100,000, the weight must be 1,000 times that of 2 kilograms is 2,000 kilograms.

Board book: 1 small cup - 10,000 capsules.

1 kg = 5 small cups - 50,000 capsules.

2 kg = 10 small cups of 100,000 capsules.

2000 kg ——— 100000000 capsules.

If 50 kilograms are packed in a big bag, and (20) bags are to be packed, is it more specific now than 10,000 cups of rice? Then a student added, that is, 2 tons of rice. There's a cart in a car, a boat in a boat, a lot in the classroom, and so on.

The students all let out exclamations, which seemed to be concrete enough.

In hindsight, I wondered if there was any other good way to do it. So I asked the students, and one of them said that they only needed to weigh the 10,000 grains in the small cup and multiply them by 10,000. It dawned on me, yes!

So I quickly weighed it and found about 200 grams. 200 times 10,000 is equal to 2,000,000 grams, which is 2,000 kilograms, which is 2 tons. Sure enough, it can be calculated.

And the results are consistent, which convinces the students that there is no doubt that this is all there is to it. In student exchanges, most students think it's easier.

Board book: 200 10000 = 2000000 grams = 2000 kg = 2 tons.

On this basis, the students independently tried to measure how thick 100 million sheets of paper are, and there are many methods, and they are real, and they all have results, which is ideal. The interest is also high, mainly because they imagined that it was only as high as a classroom, and the result was higher than Mount Everest, which was unexpected. The students seemed to be happier.

Outside of class, students also tested and extrapolated 100 million other objects. To be honest, the new course has made the students happy, but the teachers have worked hard. Although the teacher has worked hard, he has also gained something.

Do you know now? How many grains of rice are 100 million grains? After class, I talked about it with the teachers, and Mr. Jiang from the office said:

If each person saves 1 grain of rice, the whole country will be 26 tons, which is not a small number. It seems that this is a good subject for food conservation education. ”

I didn't expect math to be so fascinating, and I realized that I had done something meaningful. Who::

There are about 50,000 grains per kilogram of rice. Take out 20 pieces of rice, it's not too much Anti-weighing on the electronic scale Write down the weight Take 1000 and divide it by this gram Multiply it by 20 It's OK The rice varieties are different, and the number of rice grains in 1 gram is also different. The weight of 1,000 grains of rice is 18 34 grams, and 1 gram of rice is 1000 34 1000 18 grains, that is, 1 gram is about 29 56 grains.

Japonica rice weighs 25 32 grams per 1000 grains, and 1 gram of japonica rice is 1000 32 1000.

Conversion of one kilogram of riceOne kilogram of rice is equal to 1 kilogram of rice, which is 2 catties of rice. And 2 catties of rice, according to the quality of the rice and the origin of the different, the taste after cooking is not the same, there are more than 2 yuan a catty, there are 5-6 yuan a catty, there are also more than 10 yuan a catty, 2 catties of rice can be cooked for about 10 people, cooking porridge can be for about 20 people to eat.

There are about 4,000 capsules in 1 kg. One kilogram of rice depends on the length and thickness of the rice grains, the weight of different lengths of rice, the weight is different, the number of rice grains is different, the number of large rice grains is less, the number of small grains of rice is less, the number of coarse rice grains is less, and the number of fine rice grains is less.

meters of weightThe weight of 100 grains of rice is about 2 grams, and 1 grain of rice has grams. Take rice as an example, about 600 grains of ordinary northern rice is 50 grams, this kind of rice is high-quality rice with full grains Then, a grain of rice is one-twelfth of a gram The varieties of rice are divided into many kinds, and the weight of a grain of rice is difficult to calculate with a flat scale, we can count 100 grains of rice and then weigh it, and divide the number of grams obtained by 100 to get what the weight of a grain of rice is.

1,000 grains of rice weigh about 25 grams, and one cherry yard of 100 million grains of rice weighs about 250 kilograms.

Rice refers to the seeds of cereals or other plants that have been peeled or shelled, specifically rice. There are about 1.3 billion people in China, and if each person saves one grain of rice per day, the whole country saves about one ton of rice a day. It is calculated using a mathematical formula of addition, subtraction, multiplication and division, and the process is as follows:

100 million grains of rice approximately: 100000000 1000 25 = 2500000 (grams) = 2500 (kilograms). 1.3 billion:

2500 13 1000 = tons).

The product of several numbers can be multiplied by a number, and it can be balanced so that any factor in the product is multiplied by this number, and then multiplied by other numbers. For example: 25 3 9 4=25 4 3 9=2700.

Multiplying the difference between two numbers by one number allows the subtracted number and the subtracted number to be multiplied by this number, and then the resulting product is subtracted. For example: (137-125) 8=137 8-125 8=96.

There are about 60,000 grains of 1 kilogram of rice.

Method: 1. Weigh the weight of a small cup with a balance first, and then use a cup to hold a small cup of rice (be careful not to let the weight of the cup and rice exceed the range of the small balance), and weigh it.

2. The weight of the rice = the second weighing - the first weighing.

3. Count the number of grains of rice just weighed (here you will encounter the problem that the error is too large, and it is too troublesome to count more. ）

4. Suppose you just weigh the rice as x kilograms and there are n grains. Then 1 kg of rice has n x grains. (The unit of weight weighed by the balance is grams, and the unit needs to be unified when calculating, and the weight of the rice weighed by the balance needs to be converted into kilograms, or 1 kilogram into 1000 grams.)

Extended Information: Adulterated Rice Identification:

1.Long-grain fragrant rice.

Identification method: First of all, from the perspective of grain shape, the length of rice grains is above and the length-width ratio is more than 2:1 to be called long grains; In addition, long-grain fragrant rice should be fragrant rice, which has the natural aroma of rice, and many unscented rice are also sold as long-grain fragrant rice.

2.Fake basmati rice with flavor.

Identification method: add flavor to the rice and soak it in boiling water for 1 2 minutes, the rice has no fragrance after soaking, and the real fragrant rice still has a fragrance after soaking.

3.Add mineral oil to the rice.

Identification method: Although the inferior polished rice and the rice with mineral oil are very bright, the beige color is partial to the branches, and the mountains are dark, and there is a greasy smell.

4.Distinguish dyed rice:

Identification method: colored rice is white, but after dyeing rice, the rice heart will also have color penetration; Normal colored rice will fade slightly when cleaning, but if the color loss is severe, it may be dyed rice.

The weight of 1,000 grains of rice is between 6 (ultra-small) and 60 (Bu Zi Li super large) grams, and the generally accepted average 1000-grain weight is grams, which is about 1000 grains.

1000 grains of rice.

Approximately weighs 25 grams;

100 million grains of rice are about (2,500,000 grams);

2,500,000 (grams).

2500 (kg).

t) division operations back to properties.

The dividend answer expands (shrinks) n times, and the divisor does not change, and the quotient expands (shrinks) n times accordingly.

The divisor expands (shrinks) n times, and the dividend remains unchanged, and the quotient shrinks (expands) n times accordingly.

The dividend, divided by two divisors consecutively, is equal to the product of the two divisors. Sometimes simple operations can be performed depending on the nature of division. For example: 300 25 4 = 300 (25 4) divided by a number = the reciprocal of this number.

Weighs 2,500,000 grams, which is equal to 2,500 kilograms (kilograms).

1000 grains of rice weigh about 25 grams;

100 million grains of rice are about (2,500,000 grams);

2,500,000 (grams).

2500 (kg) = tons).

About 50,000 grains of rice per kilogram.

There are about 55,600 grains per kilogram of smaller rice, while about 43,000 grains per kilogram of larger rice. The weight of 1,000 grains of rice is about 18 to 23 grams, one kilogram is 1,000 grams, and 1,000 20 is equal to 50, so there are about 50,000 grains in one kilogram of rice. Balance and defeat.

Hello, how many grains of rice a kilogram? 1 kg = 1000 grams, 10 grams 12 grains, 1 gram = grain hand, but to convert grams into kilograms of liters, so, noisy potato hunger 1200 1000 1200000, so 1200000 grains of rice have a kilogram, please refer to!

Taking rice as an example, about 600 grains of ordinary northern rice is 50 grams, and this kind of rice is high-quality rice with full grains.

Then, a grain of rice is one-twelfth of a gram.

Then a million is a twelfth gram multiplied by 10 to the 6th power, which is about less than 100 kilograms.

A grain of rice york. The weight of 100 grains of rice is about 2 grams, so 1 grain of rice is not worth grams. The gram multiplied by 1.3 million is equal to 26,000 grams, and 26,000 grams is equal to 26 kilograms of reed eggplant, which is also equal to 52 city catties.

1 kilogram of rice is about 50,000 grains (depending on the variety of rice grains and the size of the liquid field).

1,300,000 grains of rice, = > is equal to 26 kilograms.

All, 1,300,000 grains of rice are about26 kg
