Xiaoyu was reading a science fiction novel. She had planned to finish it in 45 days, but she actually read 25 pages a day, which was 5 days shorter than her original plan. How many pages is this book?

张阿姨计划用7天看完一本小说那么她每天可以阅读小说的 $\frac{1}{7}$ 部分. 因此她5天可以阅读小说的 $\frac{1}{7}$ 的 $\frac{5}{7}$ 次方即 $\frac{1}{21}$ 的部分. 因此张阿姨5天可以阅读小说的 $\frac{1}{21}$ 的比例即 $\frac{1}{21}$ .

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.

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.

If Xiao Hong reads a children's novel and reads 12 pages a day and can finish it in 10 days, then the number of pages in this novel is: 12 pages/day x 10 days = 120 pages If I read 15 pages a day, how many days would it take to finish it? 15 pages/day x days = 150 pages To determine the total number of pages in this novel, we need to divide 120 pages by the total number of pages we read every day, 15 pages, to get: 120 pages/15 pages/day = 8 days Therefore, Little Red needed eight days to finish reading the same children's novel, which was 15 pages a day.

Xiaoxiao had been reading for 5 days and had read 11 pages a day, so she had read 11 x 5 = 55 pages in total. This novel had 154 pages, so Xiaoxiao still needed to read 154 - 55 = 109 pages. She needed to read 11 pages a day, so she needed to read 109 pages/11 pages/day = 967 days. However, since she had already started reading for five days, she needed to read for another five + 967 = 1467 days. Hence, Xiao Xiao needed about 15 days to finish reading the novel.

Zhang Li read a 290-page novel for the first four days and read 20 pages a day. She planned to read 10 pages a day for the rest of the time. Calculating the number of pages read in the previous 4 days:4 days x 20 pages/day = 80 pages. The remaining pages:290 - 80 = 210. The number of pages left per day:210 pages/10 pages/day = 21. The remaining days were 21 days. Therefore, Zhang Li needed another 21 days to finish reading the book.
