Kobayashi read a science fiction novel and read 16 pages a day. After five days, he still had three-fifths of the book left. How many pages does this book have?
Assuming that the book has a total of $x$pages, then according to the question, Kobayashi reads $16$pages a day and finishes the book in 5 days. In this way, Kobayashi needed to read $16/div2 = 8$pages in the remaining $2/5$. Because Kobayashi had watched it for a total of $5$days, he still needed to watch it for $5 - 4 = 1$days. Therefore, Kobayashi still needed to read $8$pages of this book, a total of $x$pages. According to the meaning of the question, this book has a total of $x$pages. Kobayashi reads $16$pages a day and finishes reading this book in 5 days. Therefore, there is the following equation: $$8 = \frac{x}{2} + \frac{x}{5} + 8$$ To simplify it: $$x = 100$$ So the book had 100 $pages.
Kobayashi read a science fiction novel and read 16 pages a day. After five days, he still had three-fifths of the book left. How many pages does this book have?
This book has a total of $16,000 = 80$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 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.
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.
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?
Xiao Ming reads a book every day, reads 15 pages, and after 4 days, there are still 3/5 of the book left. How many pages does this book have? Assuming that the book has a total of $x$pages, then the number of pages that Xiao Ming reads in 4 days is $15,4 = 60$pages. The remaining pages are 3/5 of the book's worth, so there are: $$ 60 \div (3/5) = 12 $$ So the book has a total of $12$pages.
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.
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 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.
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.
If you read 14 pages of a book every day, and after five days, you still have three-eighths of the book left unread, how many pages does this book have?
Let's say the book has x pages. He read 14 pages a day, so he read for a few days: Number of days = page count/page count per day = x/14 He did not read the remaining pages: Remaining pages = 3/8 of the book Therefore, there are: Remaining pages = 3/8 * x Substitute the above formula into the formula that you read on page 14 every day: 3/8 * x = 14 * x ÷ 14 To simplify it: x = 32 So this book has 32 pages.
