According to the question description, Xiaoming had read 2/5 or 60 pages while Xiaofang had read 3/7 or 420 pages. Since the total number of pages in the book is 350, the following equation can be written: Xiao Ming had already read page x, so Xiao Fang had already read page (3/7)x. 350 = x + (3/7)x 6/7x = 350 x = 350 × 7 × 6/7 x = 2800 Therefore, Xiaoming had already read 2800 pages and Xiaofang had already read 420 pages.
The total number of pages that Xiaofang had read was 56. The remaining pages were 56-1=55 pages. The number of pages that Xiaofang had read was 55×7=355 pages.
Xiaoming reads a storybook, Xiaofang reads a science book. The number of pages in a storybook is 75% of that in a science book. Xiaoming reads 15 pages a day, Xiaofang reads 18 pages a day. If Xiaoming and Xiaofang had a total of 100 pages, then they would read 100 * 15 / 100 = 15 pages a day. The remaining pages were 75% of the pages of the science book, which was 75 * 18 / 100 = 15 pages. Since the number of pages in the story book was 75% of the number of pages in the science book, the remaining pages were 75 / 75 = 1 page. Therefore, Xiaoming and Xiaofang read a total of 15 + 1 = 16 pages a day. They only read one page a day, which meant that they couldn't read the rest of the pages.
If she had read 20% of the pages of a novel and had not read 50%, then the number of pages that Xiaofang had read was: 20% ÷ 2 = 10% What I haven't seen is 50% divided by 5 = 10% The number of pages that Xiaofang has read is 10% + 10% = 20% Therefore, Xiaofang had already read 20% of the pages, and the remaining pages accounted for 50%.
Xiao Ming had already read two-fifths of a 200-page storybook, which was 10 pages more. 200 pages × 2/5 + 10 pages = 40 pages The remaining pages were: 200 - 40 pages = 160 pages Therefore, Little Ming still had 160 pages left.
Xiaofang read a storybook. The number of pages she had read before dinner was 1/7 of the number of pages she had not read. After dinner, she read another 8 pages. Assuming that the total number of pages in the storybook was 100. The number of pages read before dinner is 10 pages, the number of pages not read is 100 pages- 10 pages = 90 pages. After dinner, he read another 8 pages, so the number of pages he had read was 10 + 8 = 18. The ratio of the number of pages seen to the number of pages not seen was 18 pages/90 pages = 1/7. Therefore, Xiaofang had already read 7 pages before dinner, and the remaining pages were 93 pages. She read 8 pages after dinner, so she had read 93 pages + 8 pages = 101 pages in total.
How many pages are there in this storybook? Xiaofang had read 1/7 of page before dinner and 8 pages after dinner, so she had read 1/7 + 8 pages, which was 11/7 pages. Then this storybook had a total of (11/7) + 1 = 18/7 pages.
Xiaofang was reading a storybook. The number of pages she had read before dinner was 1/7 of the unread pages. After dinner, she read another 8 pages. At this time, the number of pages she had read was 1/7 + 8 = 19/7. Therefore, Xiaofang read 1/7 pages before dinner and 19/7 pages after dinner. 19 + 1/7 + 1/7 = 46/7 pages. Answer: Xiaofang read 1/7 pages before dinner, 19/7 pages after dinner, 46/7 pages in total.
Xiao Ming had already read two-fifths of a 30-page book, so there were 30 - 2/5 = 30 - 04 = 296 pages left. Therefore, there were 296 pages left in the book.
The Story King has 82 pages. Xiao Ming has read page A, so there are 75 pages left. The answer was that Xiao Ming still needed to read the 75-page Story King.
Li Lin had already read two-fifths of a 255-page storybook. 255/2/5 = 1225 pages Since the book had a total of 255 pages, the remaining pages were: 255 - 1225 = 1225 pages Therefore, Li Lin still had 1225 pages left.
