Zhang Li read a book with 80 pages. On the first day, she read 35% of the book, and on the second day, she read 1/4 of the book. How many pages did she read in two days?
Zhang Li read a book of 80 pages. On the first day, she read 35% of the book, and on the second day, she read 1/4 of the book. How many pages did she read in two days? On the first day, he read 35% of the book, which was 80 pages x 35% = 28 pages. The next day, he read 1/4 of the book, which was 80 pages x 1/4 = 20 pages. Therefore, the total number of pages he read in two days was 28 + 20 = 48. Answer: 48 pages in two days.
Xiaofang read a story book. On the first day, she read 51 pages of the book, and on the second day, she read 10 pages. The ratio of the number of pages she had read to the number of pages she had not read was 2:3.
On the first day, Xiaofang read the book's 51 pages, and the remaining pages were $51/div2 = 25$. The next day, he read another 10 pages and the remaining pages were $25 + 10 =$35. At this point, the ratio of pages seen to pages not seen is 2:3, which can be expressed as $25:35=2:3$. Therefore, Xiaofang had read the book for $2+3=5$days and still had $35-5=28$pages left.
Xiaofang read a story book. On the first day, she read 1/5 of the whole book, and on the second day, she read 10 pages. The ratio of the number of pages read to the number of pages not read was 2.
Xiaofang read 15 of the book on the first day and read 10 pages on the second day, so she read a total of ${1}{5} +{1 = 15}$pages. Assuming that the book has a total of $x$pages, then Xiaofang has read a total of $x \times \frac{1}{5} + x \times \frac{10}{1 = 10x + 50}$pages. At this time, the ratio of the number of pages read to the number of pages not read is 2, which means that the number of pages left by Xiaofang is twice the number of pages in the book, which is $x/times 2 = 10x + 50$. The solution is $x = 105$, which means that the book has 105 pages. Xiaofang read 15 pages on the first day and 10 pages on the second day. She read 25 pages in total.
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.
Lili read a storybook. She read 78 pages in the first 3 days and 40 pages a day in the next 4 days. how much of this book
Assuming the book has a total of n pages, Lili read 78 pages in the first 3 days, then there are still n - 3 × 78 = n - 262 pages not read. In the next four days, she read an average of 40 pages a day. In these four days, Lili read a total of 40 × 4 = 160 pages. Therefore, Lili had read a total of n - 262 + 160 = 322 pages, just enough to finish the book. So this book had 322 pages.
Xiao Hong read a book. On the first day, she read 25% of the total pages of the book. On the second day, she read two-fifths of the total pages of the book. There were still 35 nights left.
On the first day, Xiao Hong read 25% of the total number of pages in the book, which was 1/4. The next day, Xiao Hong read half of the book's pages, which was 1/8. The remaining pages were 35% of the total number of pages in the book, which was 1/4 * 35% = 75%. Thus, the book had a total of 160 pages.
Xiao Hong read a book. On the first day, she read one-fifth of the total number of pages. On the second day, she read another 30 pages. There were still 42 pages left. How many pages were there in this book?
On the first day, Little Red had read one-fifth of the total number of pages, which was one-fifth of the page. The next day, he read another 30 pages, so the remaining pages were the total number of pages minus 30 pages: 42 - 30 = 2 pages Therefore, the total number of pages in this book was five.
Wang Ying read a story book. On the first day, she read 10/1. On the second day, she read 16 pages more than the first day.
The number of pages read is the number of pages read on the first day plus the 16 pages read on the second day. Number of pages viewed = 10/1 + 16 = 16 + 10/1 = 26 + 10/1 = 36 Therefore, Wang Ying had already read 36 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.
Zhang Li read a 290-page novel. For the first four days, she would read 20 pages a day. For the rest of the time, she planned to read 10 pages a day. How many more days would it take to finish the book?
Zhang Li read a 290-page novel for the first four days and read 20 pages a day. She planned to read 10 pages a day for the rest of the time. Calculating the number of pages read in the previous 4 days:4 days x 20 pages/day = 80 pages. The remaining pages:290 - 80 = 210. The number of pages left per day:210 pages/10 pages/day = 21. The remaining days were 21 days. Therefore, Zhang Li needed another 21 days to finish reading the book.
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.
