Xiao Hong had read a book. She read 24 pages a day. After five days, she still had 40% of the book left. How many pages was this book?
Little Red read 24 pages a day for 5 days, so how many pages did she read in total: 5 days x 24 pages/day = 120 pages The rest of the book takes up 40% of the whole book, so the remaining pages take up: 40% ÷ 100% = 04 The pages of the book were: 120 pages/04 = 300 pages So this book has 300 pages.
Xiao Xiao read a book. She read 20 pages a day. After 5 days, she still had 60% of the book left. How many pages is this book?
Assuming that this book has $n$pages and Xiaoxiao reads $20$pages a day, then she reads a total of $/frac{20/times 5}=50$pages. The rest of the books have a total of $n-50$pages, where $/frac{60}{n}$represents the proportion of the number of pages in the book. If the ratio is simplified to $\frac{60}{n}=\frac{n-50}{n}\times 100$, then $n=1200$. So this book is $1200$pages.
Xiao Hong read a book and read 15 pages a day. After four days, she still had three-fifths of the book left. How many pages was this book?
Let's say the book has $x$pages. Reading 15 pages a day, it would take Xiaohong $x$days to finish reading this book. The remaining pages were three-fifths of the book, which was $025x$. According to the question, it would take Xiaohong four days to finish reading this book. Therefore, we can write the equation: $$ x + 025x = 025 \times (x+4) $$ Solve this equation: $$ x = 30 $$ So this book has 30 pages.
Little Red read a book and read 15 pages a day. After four days, she still had 3/5 of the book left. How many pages was this book?
Assuming that the book has a total of $x$pages, then Little Red has read $x/times 15$pages in 4 days. The remaining pages are 3/5 of the book's worth, so there are: $$x <times 15><times 3/5>= Total pages $$ Solve this equation: $$x = \frac{total pages}{15} = \frac{1200}{15} = 80$$ Therefore, the book had a total of 80 pages.
Little Red read a book and read 15 pages a day. After four days, she still had 3/5 of the book left. How many pages was this book?
Little Red reads a book 15 pages a day, and after 4 days, there is still 3/5 of the book left. We can assume that this book has x pages. According to the question, Little Red had read a total of $4/times 15 = 60$pages in 4 days. The remaining pages are 3/5 of the book, so there are: $$ 60\div 3/5=24 $$ Therefore, the book had 24 pages.
Xiao Hong read a book and read 15 pages a day. After two days, there was still 60% of the book that she had not read. How many pages was this book? Ask for detailed steps
Little Red read 15 pages a day and had read 60% of the book in two days. Therefore, there were still 60%/15 = 4 pages left. The remaining four pages were read by Little Red every day for the remaining six days. Therefore, if you read one page a day, you can finish the remaining four pages in four days. 4 × 1 = 4(pages) Therefore, this book had a total of four pages.
Question: Xiao Hong borrowed a book. After reading it for five days, there were still 12 pages left. Xiao Hong had to return the book in three days. How many pages did she read on average every day?
Xiao Hong borrowed a book and read it for 5 days. There were still 12 pages left, so she had read a total of $5+12=17$pages. Little Red had to return the book in 3 days, so the number of pages she needed to return was $17+3=20$pages. We can calculate the average number of pages of the remaining pages per day using the following formula: $$ Remaining pages = total pages-number of pages already seen $$ Since Little Red had already read 17 pages, the remaining pages should be $17- 17> times 2=0$per day. Therefore, Little Red had to read an average of 0 pages a day.
Huan Huan had read a book. She read 15 pages a day. After four days, she still had three-fifths of the book to read. How many pages was this book? answer
This book had a total of 15 × 4 = 60 pages.
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 Dong read a book and read 24 pages a day. After 6 days, there were still 3/5 of the book that he had not read. How many pages was this book?
Assuming that the total number of pages in this book is X, then according to the information given in the title, the following equation can be written: Xiao Dong reads 24 pages a day, so he reads a total of $24/times 3 = 72$pages After 6 days, there are still 3/5 of the book left, so there are still $X <br><br><br> By equating the two equations in the system of equations, one could obtain: $$24 \times 3 = \frac{X}{5}$$ Solution: $$X = 72 \times 5 = 360$$ Therefore, the total number of pages in this book was 360.
Xiao Ming 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 does this book have?
Xiao Ming read a total of $4/15 = 60$pages in 4 days. The remaining pages are $2/5$of the book, so the book has a total of $2/5/60 = 48$. Thus, the book had a total of 48 pages.
