Xiao Xiao read a science book on the first day and read 30 pages, which is two-fifths of the book. How many pages has Xiao Xiao not read yet?
Your question is a little unclear. Can you provide more context information? For example, what is the "book" that you are referring to and why did Xiaoxiao read it? This way, I can better help you answer your questions.
A book has 170 pages. How many pages has Xiao Jun not read yet?
There are 170 pages in a book. You can get the answer by calculating the length of each page. The length of each page usually refers to the length of each page. The number of pages may vary according to different publishing houses and different format. Usually, the length of each page is 255mm or 305mm, but some books use different size. Therefore, for a 170-page book, each page is 255 millimeters long, so the number of pages in the book is: 170 pages/255mm/page = 692 pages Therefore, Xiao Jun still had about six pages to read.
A storybook has 200 pages. Xiao Ming read two-fifths of it on the first day and 15% on the second day. How many pages are left?
Xiao Ming read two-fifths of the page on the first day. The next day, he read 15%, which was page 015. Therefore, the remaining pages were 200 - (2/5 + 015) = 200 - 045 = 19545 pages. Therefore, Little Ming still had 19545 pages left.
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 Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?
Let the total number of pages in this book be x pages: - I read 3/5x pages on the first day. -20% read the next day =02x pages. According to the meaning of the question, the remaining pages were x-(3/5x+02x)=20 pages. Substituting x=50 pages gives: - I read 3/5 x 50 pages =30 pages on the first day. - The next day, I read 02 x 50 pages =10 pages. Therefore, the book had a total of 50 pages.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?
The total number of pages in this book is x. On the first day, I read three-fifths of the total number of pages, which is 3/5x pages on the first day. Reading 20% the next day meant reading 20% x 3/5 x = 2/5 x pages. Because he read 2/5x pages the next day, the remaining pages were 1 - 2/5x = 3/5x pages. Because Kobayashi read 3/5x pages, the total number of pages Kobayashi read was 3/5x + 2/5x = 5/5x pages. And because there were still 20 pages left in Kobayashi's book, 20 = 3/5x + 2/5x solved the equation to get x = 120. So this book has 120 pages.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages, and on the second day, he read 20%. How many pages is this book?
The information you provided is not detailed enough to determine the total number of pages in this book. Please provide more information so that I can answer your questions.
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 Hong had already read 40 pages of the book, which was exactly two-fifths of the book. How many pages were left?
If Xiao Hong had already read 40 pages of a book, which was two-fifths of the book, then Xiao Hong had already read 20% or 0.2 times the book. How many pages are there in the book? You can divide the number of pages by the number of pages in the book: (100% - 02) / 100% = 90% Therefore, Little Red only had 10 pages left.
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 Xiao was reading a 150-page book. She had already read two-fifths of the book. How many pages were left?
If Xiaoxiao had already read two-fifths of a 150-page book, then she had already read 150 × 2/5 = 60 pages. The remaining pages were 150 - 60 = 90 pages. Hence, Xiao Xiao still had 90 pages to read.
