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.
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, there were still three-fifths of the book that she had not read. How many pages was this book?
Little Red reads 15 pages a day for 4 days and still has 3/5 of the book left. She can write the following equation: Remaining pages/pages per day = 3/5 of the book Solve the equation: Remaining pages = 3/5 x pages of the book Substituting the remaining pages into the original book's page count, he obtained: 3/5 x pages of the book = 15 pages Therefore, this book had: 15 pages × 3/5 = 15 pages/3/5 = 150 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.
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.
Little Red was reading a fairy tale book. Every day, she would read 15 pages. After four days, she still had 3/5 of the book left. How many pages was this fairy tale book?
Little Red read a fairy tale book for 15 pages a day. After four days, she still had 3/5 of the book left. Assuming that this fairy tale book has a total of x pages: Little Red read a total of 4x15 = 60 pages in four days. The remaining pages are 3/5 of the book, so there are: 60 pages/(3/5) = 120 pages. Therefore, this fairy tale book had a total of 120 pages.

Little Cong read a book and read 15 pages a day. After four days, there were still three-fifths of the book that he had not read. How many pages was this book?
Suppose the book has x pages: Little Cong read 15 pages a day for four days, a total of 4×15=60 pages. The total number of pages in the book is x, so: 60÷(1+3/5)=x÷5 The solution was:x=60×5 div3 =600 div3 =200 pages. Therefore, the book had a total of 200 pages.
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?

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.
Little Ming read a book and read 15 pages a day. After four days, there were still three-fifths of the book that he had not read. How many pages did this book have?
