Xiaofang was reading a 175-page science book, nine pages a day, starting from August 12th. Could he finish reading the book before September 1st?
Xiaofang reads a 175-page science book, nine pages a day, starting from August 12th. Can he finish reading this book before September 1st? Although she read nine pages a day, Xiaofang needed to finish 175 pages to get a total of 264 pages of reading progress. Therefore, Xiaofang needed to read a total of 264 pages between August 12th and September 1st, which was about 10 days. Xiaofang could read 9 pages a day, so she needed to read 18 pages a day to catch up. Xiaofang needed to read 180 pages in 10 days, which was three days longer than reading nine pages a day. Therefore, Xiaofang needed to finish reading 180 pages by August 31st. In summary, Xiaofang could finish reading this book before September 1st.
Read a 100-page book, nine pages a day, starting on August 22nd. Can he finish the book by September 1st?
Read a 100-page book, nine pages a day, starting on August 22nd. Can he finish the book before school starts on September 1st? It was difficult to guarantee that he could finish reading the book before school started on September 1st because reading only nine pages a day was relatively slow. It would take a few days to finish reading the book, depending on the reading speed and time. If one could read nine pages a day and maintain a high efficiency reading habit, it would take about 10-15 days to finish the book before school started. Of course, this was only a rough estimate. The exact time needed to be calculated according to the actual situation.
Xiaoming read a story book, Xiaofang read a science book. The number of pages in a story book was 75% of that in a science book. Xiaoming read 15 pages a day, Xiaofang read 18 pages a day...
Dongdong reads 108 pages of a book, reading 9 pages a day, starting from August 20. He can finish reading this book before school starts on September 1
Dongdong read a book with 108 pages, nine pages a day, starting from August 20th. He could finish the book before school started on September 1st. Calculating that it would take 108 pages to read 9 pages per day, 9 pages per day = 12 days. Since it started on August 20th, one more day was needed: 108 pages/9 pages/day + 1 day = 12 days Therefore, Dongdong needed 12 days to finish reading this book. He could focus on speeding up his reading in the last few days before school started and try to meet the deadline.
Li Qing is reading a 128-page storybook. He reads 10 pages a day starting from August 20. Can he finish the book before school starts on September 2nd?
Li Qing needed to read 10 pages a day for a total of $128 $days. Since he needed to study for 30 days, he needed to rest for another three days. August 20th to the 30th day, before school started on September 2nd, they needed to rest for three days. Therefore, Li Qing needed to start reading on September 6th (Day 31). Li Qing needed to read $128+3+ 3 + 3 + 3 + 3 + 3+3=20$days to finish reading this book. Therefore, he needed to start reading on September 6th and finish reading the book before September 18th (the 25th day).
Xiao Ming reads a book with a total of 125 pages. He reads 10 pages a day, starting from August 20th. Can he finish reading this book before September 1st?
It is difficult to accurately predict whether Xiao Ming will be able to finish reading the 125-page book between August 20th and September 1st. This is because the speed of reading, the time spent reading, and other factors may affect his progress. However, we can do some analysis and estimations. Reading 10 pages a day meant that Xiaoming would need to spend about 125 days a day to finish reading a 125-page book. Taking into account the time he can spend every day, we can cut this time in half, which is 275 days a day. The number of days that Xiao Ming needs to read between August 20th and September 1st is: August 20-August 29 = 5 days August 30-September 5 = 5 days September 6-September 10 = 3 days September 11-September 15 = 2 days September 16-September 18 = 1 day September 19-September 23 = 2 days September 24-September 27 = 1 day Therefore, Xiao Ming needed to spend about nine days to finish reading the book before September 1st. Although this estimation result is not accurate to the end of the day, it can help us roughly predict whether Xiao Ming can complete the reading task within the specified time.
A fairy tale book had a total of 86 pages. Xiaofang had been reading it for five days, and there were still 36 pages left. How many pages does Xiaofang read on average every day
Xiaofang had been reading for 5 days and there were 36 pages left, so she had read a total of $5/36 = 180$pages. Xiaofang still needed to read $86 - 180 =-104$pages every day. Because the number of pages was negative, Xiaofang read an average of $${-104}$pages per day.
Lili is reading a 90-page fairy tale book. How many pages are there left? I read eight pages a day, and he has been reading for nine days.
The book had a total of 132 pages. After reading it for five days, there were still 72 pages left. How many pages does Xiaofang read on average every day? If you can only borrow it for 9 days, starting from the 6th day
How many pages does Xiaofang read on average every day? You can use the following information to calculate how many pages she read before the sixth day: From the sixth day onwards, Xiaofang needed to return the book, so she needed to read 132 - 72 = 60 pages every day. Xiaofang read (60 x 6) / 7 = 48 pages before the sixth day. Therefore, Xiaofang read (48 + 60) / 2 = 32 pages on average every day. Answer: Xiaofang reads an average of 32 pages a day.
Xiaofang has read 80 pages of a science book, and there are still 31 pages left. What she has read accounts for a few of the total pages of the book
The total number of pages in this book was 80 + 31 = 111. Therefore, the number of pages that Xiaofang had read accounted for the total number of pages in this book: 111 pages = 1 / 11 In other words, the number of pages that Xiaofang had read accounted for 1/11 of the total number of pages in the book.
Xiaofang read a story book. On the first day, she read 1/5 of the whole book, and on the second day, she read 10 pages. The ratio of the number of pages read to the number of pages not read was 2.
Xiaofang read 15 of the book on the first day and read 10 pages on the second day, so she read a total of ${1}{5} +{1 = 15}$pages. Assuming that the book has a total of $x$pages, then Xiaofang has read a total of $x \times \frac{1}{5} + x \times \frac{10}{1 = 10x + 50}$pages. At this time, the ratio of the number of pages read to the number of pages not read is 2, which means that the number of pages left by Xiaofang is twice the number of pages in the book, which is $x/times 2 = 10x + 50$. The solution is $x = 105$, which means that the book has 105 pages. Xiaofang read 15 pages on the first day and 10 pages on the second day. She read 25 pages in total.
