Little Light read from page 10 to 19 today, so he read page 9 today.
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 Lin was reading a 120-page storybook. He had already read 5/6 of it. How many pages are left?
Xiao Hua read a 270-page children's storybook. In the first three days, he read an average of 38 pages a day, and the rest took 4 days to finish.
Little Light read a 270-page children's storybook for the first three days and read an average of 38 pages a day. 270 pages/3 = 92 pages/day 4 days/4 = 1 page/day Therefore, Little Light read an average of 92 pages per day- 1 page = 81 pages. In the first three days of reading this book, Little Light read a total of 3 × 38 pages = 114 pages. In the remaining four days, he read a total of 4 × 1 pages = 4 pages. Therefore, the total number of pages Little Light read was 270 - 114 = 156. Little Light read an average of 92 pages a day, so the total time he spent reading this book was 156 pages/92 pages/day = 16 days. Therefore, Little Light read the book at a speed of about 16 pages per day.
How many pages of the 120-page storybook did Xiao Ming not finish reading?

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.

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.
