An extra-cursory book had 120 pages. How much of the book could Xiaoming finish in five days? After reading for three days, there are still a few parts of the book that have not been read
Xiao Ming could finish reading this book in five days. He read an average of 120 pages/5 = 24 pages per day. If Xiao Ming used three days to finish reading the book, then the number of pages he read every day would be 120/3 = 40 pages. Therefore, the remaining portion of the book could be calculated as: 1 - 40/24 = 6/24 Therefore, the average score for those who did not read the book was 6/24 = 1/4.

Xiaoli planned to finish reading a science fiction novel with 300 pages in 20 days. She read a few parts of the book every day. After 12 days, how many pages were left?
Xiaoli planned to finish reading the book in 20 days, so the number of pages she needed to read every day was: 300 pages/20 days = 15 pages/day Xiaoli used 12 days to finish reading this book, so the total number of pages she read was: 12 days x 15 pages/day = 180 pages How many pages of the book are left? We can divide the remaining pages by the number of pages we read every day: (300 pages- 180 pages)/(15 pages/day + 15 pages/day) = 10 pages/day Therefore, after reading for 12 days, Xiao Li still had 10 pages left.
Xiao Ya planned to finish reading a book in 20 days and read 15 pages a day. If he read five more pages a day, how many days would he be able to finish it?
If he read five more pages per day, the total number of pages per day would be 15 * 5/5 = 30 pages. The total number of pages that Xiao Ya needed to read in 20 days was 30 * 20 = 600 pages. If you read 15 pages a day, the total number of pages you need to read is 600 * 15/15 = 600 pages. Therefore, if you read five more pages a day, you can finish the book faster. The answer was: Ya-chan could finish the book in 15 days. She could read five more pages a day, and a total of 30 more pages, so she only needed 20-15=5 days to finish it.
Xiao Ming planned to read a novel every few days. If he read 60 pages a day, he could finish it five days earlier. If he read 40 pages a day, he would have to finish it three days later.
Xiao Ming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. Calculating how much faster reading 60 pages a day was than reading 40 pages a day: Reading 60 pages a day is better than reading 40 pages a day, reading 40 pages per hour, 60 pages = 067 hours Therefore, the total time Little Ming needed was: 1/067 = 1667(hours) 5 days ago 1667/067 = 28(hours) Days of delay Therefore, Xiao Ming needed 28 hours to finish reading this novel, which was longer than expected. Next, we can calculate the ratio of reading 60 pages a day to reading 40 pages a day, reading 40 pages per hour, reading 60 pages = 067 hours 's progress: Reading 60 pages a day is better than reading 40 pages a day. Reading 60 pages per hour/40 pages = 15 hours Therefore, the total time Little Ming needed was: 1 × 15 = 0667(hour) 5 days ago 0667/15 = 04(hours) Days of delay Therefore, Xiaoming needed four hours to finish reading this novel, which was shorter than the estimated time. To sum up, Xiaoming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. If reading 60 pages a day was faster than reading 40 pages a day, reading 40 pages per hour, reading 60 pages per hour = 067 hours, the total time required was 1667 hours; if reading 60 pages a day was slower than reading 40 pages a day, reading 60 pages per hour, reading 60 pages per hour = 15 hours, the total time required was 0667 hours.

18 pages a day, 14 days to read and play. If you finish reading it five days in advance, how many pages should you read every day?
If you read 18 pages a day, it would take you 14 days to finish it. If you want to finish the book 5 days earlier, you need to shorten the number of days to 10 days. 5 days earlier is equivalent to reading 18 pages less per day, so you need to read 24 pages per day (14 days-5 days =10 days).
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.
