Li Xin wanted to read a 600-page children's fairy tale. She planned to finish it in 12 days, but she actually read 40% in 6 days. According to this calculation, Li Xin could finish reading it in a few days…
According to the topic, Li Xin planned to finish reading Children's Fairy Tales in 12 days, but in fact, she read 40% in 6 days. Then the number of pages he read in the first six days was: The number of pages read in the previous 6 days/total number of pages = 40%/600 = 0067 In other words, the number of pages he read in the first six days accounted for 0.67% of the total number of pages, which was six pages. Therefore, Li Xin needed to choose 5 out of the 6 pages to be his main text, and the remaining 1 page could be used as a reference or an attachment. For the remaining page, he needed to calculate how many pages he needed to read every day: 1 page × 6 days = 001667 Because the total number of pages that needed to be read every day was six, so: 001667 ÷ 6 = 0002833 He needed to read page 0002833 every day. Therefore, Li Xin needed to read page 0002833 every day for the next 6 days to finish the last page. If you want to calculate the total number of days you need to read, you need to multiply the total number of pages you need to read per day by the number of days: (0002833 ÷ 6) × 12 = 0004867 Therefore, Li Xin needed 12 days to finish reading Children's Fairy Tales.

For a book, if he had read 170 pages in the first 10 days, at this speed, he would be able to finish it in another 8 days. How many pages was this book?
Assuming that the book has a total of x pages, then based on the 170 pages read in the previous 10 days, we can get: Day 1 - 10 days = 170 pages Day 2 - 11 = 180 pages Day 3 - 12 days ago = 190 pages Day 10-First 10 days = 170 pages Therefore, the book had a total of x pages that could list an equation: x = (170 + 180 + + 190) / 10 To simplify it: x = (1700 + 190n) / 10 Where n was the number of pages read on the 10th day. Because on the 10th day, I watched it for 8 days, so there were: n = 8 Substituting n into the above formula: x = (1700 + 190*8) / 10 x = (1700 + 1564) / 10 x = 2264 Therefore, this book had a total of 2264 pages.
