Analysis: 4000307 can be divided into two levels according to the four-digit classification: level 1 and level 10,000. 0307 is a grade, and 4 million is 10,000 grades. Read according to integer reading method.
Starting from the high position, read 10,000 levels first, then read another level, read the number of 10,000 levels, and then add a word "10,000" after it according to the reading method of series, and don't read zero at the end of each level. There is a zero or several zeros in the middle of the number, and only one zero is read.
Extended data:
According to the four-digit classification principle, China's reading rules are:
1, numbers within four digits, read from the high places in numerical order.
2. Numbers with more than four digits should be graded according to four digits from right to left, and then read from the highest level to one billion, ten thousand and one level in turn. Read the numbers in each level and their level names. The number in the billion-level is read according to the reading method of the single-level median, and then the word "billion" is added at the back; The numbers in the ten thousand grades should be read according to the reading method of the middle numbers at all levels, and then the word "ten thousand" should be added at the back;
3. No matter how many zeros are at the end of each level, don't read them; There is a "0" or several "0" on other numbers, all of which are read-only zeros.
How to write multiple numbers:
1, write it down step by step in numerical order, starting from the high position. There are three levels in the number of billion-level, first write billion-level, then write million-level, and finally write one level; There are only two levels in the number of ten thousand levels. You write Level 10,000 first, and then Level 1. Write a few numbers on the writer.
If there is no number on any number, write a zero on that number.
