Li Mingpan read 1/3 of the total page of a storybook on the first day, and read 2/5 of the total page on the second day. How many parts are left?
Li Mingpan had read 1/3 of the total page on the first day and 2/5 of the total page on the second day. Total page count-1/3 of the total page count on the first day-2/5 of the total page count on the second day = total page count-1/3 of the total page count on the first day- 2/3 × total page count = 2/3 × total page count Therefore, the book still had 2/3 x total pages = 4/9 pages left.
Xiao Xiao was reading a 96-page storybook. On the first day, she had read 1/4 of the total number of pages. On the second day, she had read 3/8 of the total number of pages. On the third day, which page should she start reading?
According to the knowledge of online literature enthusiasts, we can calculate that 1/4 of the total number of pages read on the first day is 96 pages/4 = 24 pages. The next day, he read 3/8 of the total number of pages, which was 96 pages/8 = 12 pages. Hence, the number of pages Xiao Xiao had left on the first night was 96 - 24 - 12 = 62 pages. In that case, Xiaoxiao should have started from page 62, which was the remaining pages from the first day. Therefore, he should start reading from page 62 on the third day.
A 180-page book, read two-fifths of the total, the next day read one-third of the total, how many pages are left
If a book had 180 pages and two-fifths of the total number had been read, then there would be 180 × 2/5 = 72 pages left. The next day, he read one-third of the total, so he had 180 × 3/10 = 24 pages left. Therefore, there were 72 + 24 = 106 pages left in the book.
Xiao Ming read a 480-page storybook and read page A every day for 12 days. How many pages are left?
When Xiao Ming read page A of the storybook every day for 12 days, he had read a total of 12 × page A. Therefore, when Xiaoming reads a 480-page storybook, he still has 480 - 12 × a pages left. To calculate the remaining pages, he needed to know how many pages Xiao Ming read in the end and how many pages he read every day. If we assume that the last page that Xiao Ming read was 480 pages and he reads page a every day, then we can write the following equation: 480 - 12 × a = Remaining pages By solving this equation, we can get: Remaining pages = 480 - 12 × a = 480 - 12a Therefore, after reading page A for 12 days, Xiao Ming still had 480 - 12A pages left.

Xiao Hong looked at a storybook. On page 13, there were a total of 18 lines with 38 words per line. How many words were there on this page?
Xiao Hong looked at a storybook. On page 13, there were 18 lines with 38 words per line, so each page had a total of $18,38 = 720$words. Because Xiao Hong saw that this storybook already had 13 pages, there were about 200 words on this page: $720/div200 = 36$words/second In other words, Little Red could read about 36 words in this storybook every second. If Little Red's speed was 5 words per second, then this page would have about $720/div5 = 144$words. Therefore, Little Red saw that there were a total of 144 words on page 13 of this storybook.
A 600-page storybook. Nono would read 28 pages a day. Could he finish it in 19 days?
Reading 28 pages a day in 19 days can finish a 600-page storybook, but you need to pay attention to the following points: 1 The total number of pages in a storybook is 600, and reading 28 pages a day is actually only 28/2 = 14 days to finish reading each page. Therefore, he needed to divide 19 days by 14 days to determine the total number of pages he could read. The answer was that they could finish reading it, but they needed more time. If you read 28 pages a day, you would need 14 days to finish the story book. If Nono only reads 1 page in the remaining 14 days, she will not be able to finish the storybook. Therefore, Nono had to ensure that he could read a certain number of pages every day to ensure that he could read the entire story book. Reading 28 pages a day would take 14 days to finish a 600-page storybook. In the remaining 14 days, he had to ensure that he could read a certain number of pages every day in order to read the storybook completely.
How many pages were there in the storybook? Xiaoming had read 28 pages on the first day, and on the second day, he had read 1/5 of the total number of pages. There was still 1/3 of the total number of pages left?
Little Min read a 900-page storybook. On the first day, she read 124 pages. On the second day, she read 37 pages less than the first day. On the third day, which page should she start reading?
Little Min read a 900-page storybook, and on the first day, she read 124 pages. On the second day, she read 37 pages less than the first day. Assuming Min reads x pages the next day, the number of pages left on the second day is 900-x. According to the first day of reading page 124, the following equation can be listed: 124 + x = 900 - x + 37 Solve the equation: 151 = 867 Therefore, the number of pages that Little Min read on the third day should be a multiple of 867. Since 900 is an even number, 867 is a multiple of 900, so Min should start reading from page 867.
Xiao Hong read a 60-page storybook. On the first day, she read one-fifth of the book, and on the second day, she read one-fourth of the book.
On the first day, Xiao Hong read one-fifth of the book, which was 60 pages x 1/5 = 12 pages. The next day, Xiao Hong read a quarter of the book, which was 60 pages x 1/4 = 15 pages. Therefore, Little Red read a total of 12 + 15 = 27 pages on the first and second day.
