8970000 How many billions write decimals?

This is equal to 100 million.

1. Do a good job of pre-class preparation and find out what you don't understand.

2. Follow the teacher's ideas closely in class, and focus on listening to what you don't understand during the preview.

3. After class, carefully complete the homework assigned by the teacher, and if there are any questions that you can't do, immediately review the relevant content in the textbook and recall how the teacher talked about the content during class. After understanding the relevant textbook knowledge, it is natural to do the questions.

Fourth, take good notes of the class, including the key points and difficult points, so that you can recall what the teacher said immediately after class. After that, review again one hour, review a third time after 12 hours, and consolidate one day later, two days later, five days later, eight days later, and fourteen days later. In this way, you can ensure that you must pass the monthly exam.

Then review it twice at the end of the semester and you will be able to remember it for a long time.

5. Establish a wrong question book. Every time you review, you focus on mastering the knowledge involved in the wrong questions to improve your learning efficiency.

1. Thinking: Thinking is at the heart of the mathematics learning method. In this course, thinking has a lot of significance.

When solving a math problem, you must first observe, analyze, and think. Thinking can often discover the characteristics of the problem, find out the breakthrough of the problem, and the easy way to solve the problem. Around us, all the students who really learn well have the habit of thinking diligently and often using their brains, so the more their brains are used, the more agile they are, and the diligent thinking becomes good at thinking.

It is because of my mastery and application of this method that I won the first prize in Wuhan in the National Mathematics Competition.

2. Try it out: Hands-on help to digest the knowledge learned and achieve a thorough understanding. After class, I often deduce the formulas that the teacher has taught, and do not read books when deriving, but memorize them.

In this way, you can master the formula and lay a solid foundation for the calculation of formula deformation.

3. Cultivating the spirit of creativity: The so-called creation is to come up with new methods, make new achievements, and establish new theories. Creation is not limited to the methods taught by teachers and textbooks.

Usually, there are some difficult questions, and after I understand the methods explained by the teacher, I have to find out if there is another solution, so that I can deepen my understanding of the problem, compare the pros and cons of several solutions, and make the problem-solving thinking reach a higher level.

100 million = 1000000000, 1 = 1 1000000000000000000000000000000000000000000000000000000000000000000000000000

So Yu Qinchi, 7450002000 = 7450002000 1 10000000000000000000000000000000000000000000000000000000000000000000 Hundred million.

Solution: 98600000 = 100 million.

Answer: The number rewritten in billions is.

Generally, the number will be retained, like the above is billion, if it is clear that it is estimated to be million, it is billion.

Billion keep a small number of billions.
