Xiao Hong read a storybook. On the first day, she read 30 pages, which happened to be a quarter of the book. On the second day, she read a third of the book.
The next day, Little Red finished reading 30 pages of the book. The remaining pages were 1-1/4=3/4 pages of the book. On the first day, Little Red finished reading 1/4 of the book. The remaining pages were 3/4-1/4=1/4 pages. The next day, Little Red finished reading 1/4 of the book. The remaining pages were 1/4-3/4=1/4 pages. Therefore, Little Red finished reading 1/4+1/4=1 page of the book in two days.
Xiao Hong read a book with 95 pages for five days. Xiao Li read this book with 30 pages a day. On average, how many pages did Xiao Hong read less than Xiao Li every day?
Xiao Hong spent a total of five days reading this book and had read a total of 95 pages. Xiaoli read 30 pages a day for a total of 5 days, so Xiaoli read a total of 30 × 5 = 150 pages. Then how many pages does Xiao Hong read less than Xiao Li on average every day? The total number of pages that Xiao Hong read was 95. The total number of pages that she read every day was 95/5 = 19. The total number of pages Xiao Li read was 30 x 5 = 150 pages. The total number of pages she read every day was 30 pages. This was because Xiao Hong read 19 - 30 = -1 pages less than Xiao Li every day. Therefore, Xiao Hong read an average of 19 pages less than Xiao Li every day.
Xiao Liang read a storybook, read 25 pages a day, and after 4 days, there were still 3/5 of the book that he had not read. How many pages does this storybook have?
Assuming that this storybook has a total of $x$pages: - Xiao Liang reads $25$pages every day, so how many days did he read in total:$x 25$days - After 4 days of reading, Liang still has 3/5$of the book left, so he still has 3/5 times x$pages left. - Therefore, there were pages that were not seen by Xiao Liang. The simplified version was $x = 1250$pages. Therefore, this storybook had a total of 1250 pages.
A storybook has 72 pages. Xiao Hong has read 24 pages. Please use the simplest score to express the number of pages that Xiao Hong has read and the number of pages that she has not read.
The number of pages that Little Red had read and the number of pages that she had not read accounted for the total number of pages: Number of pages seen:24/ 72 = 033333333 Unread pages:72 - 24 = 48/ 72 = 066666666 Therefore, the number of pages that Little Red had read and the number of pages that she had not read accounted for the total number of pages: Number of pages seen: 033333333/066666666 = 05 embarrass50% Unread pages: 066666666/066666666 = 10 embarrass100% Therefore, the number of pages that Little Red had read and the number of pages that she had not read accounted for about 50% and 100% of the total number of pages.
Xiao Hong read a 60-page storybook. On the first day, she read one-fifth of the book, and on the second day, she read one-fourth of the book.
On the first day, Xiao Hong read one-fifth of the book, which was 60 pages x 1/5 = 12 pages. The next day, Xiao Hong read a quarter of the book, which was 60 pages x 1/4 = 15 pages. Therefore, Little Red read a total of 12 + 15 = 27 pages on the first and second day.
Xiao Qiang read a storybook and read 20 pages a day. After five days, he still had one-fifth of the book left unread. How many pages was this storybook?
Let's say this storybook has $x$pages. He reads $20$pages every day, so Cockroach reads $20/times 5 = 100$pages. The remaining pages were one-fifth of the book, which was $025 x = 100$. The solution is $x = 400$. So this storybook is $400$pages.
A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a week?
Xiao Hong read a book and read 15 pages a day. After 4 days, she read three-fifths of the book. How many pages does this book have?
Assuming that the book has a total of $x$pages, how many pages has Xiaohong read in 4 days? Based on the 15 pages she read every day, she read a total of $15,4 =$60 pages. Then she read three-fifths of the book, which means that she only read the $3/5 part of the book. Therefore, we can write the equation: $$60 = 3/5 \times x$$ To solve this equation, you can get $x = 60 times 5/3 = 100$. Therefore, the book had a total of 100 pages.
Xiao Hua read a book and read 15 pages a day. After reading for 4 days, he still had 2/5 of the book left. How many pages of this storybook had he not read?
Assuming that this storybook had $x$pages, then the number of pages Little Light read every day was $15/div4 = 375$pages. Little Light had already read $4$for days, so the remaining pages were $x - 4/375 = x - 1125$. Because the number of pages Little Light reads every day is fixed, the number of pages can be expressed as: $$x - 4 \times 375 = 375 \times 4 - 1125$$ The above formula was simplified to: $$x = 48$$ Therefore, there were still $48 - 1125 = 3675 pages of this storybook that he had not read.
A storybook had 250 pages, and Xiao Ming read 15 pages a day. Could he finish it in two weeks?
Little Light read a storybook and read 60 pages a day. After three days, he still had 5/8 of the book left. How many pages was this storybook?
Let's say this storybook has a total of $x$pages. Reading $60$pages a day, the number of pages Little Light read in $3$days was: $$60\times3=180$$ The remaining pages are 5/8 of the book, so the following equation can be written: $$x\div5=8\times60\times3$$ Solve this equation: $$x=2400$$ So this storybook had a total of $2400 pages.
