One day: 1. Read novels, 2. Sit and read, 3. Lie down and read. He had been watching it all day!
She spent the entire day reading novels.
Dongdong read a book on the first day, the ratio of the number of pages he had read to the number of pages he had not read was 2 to 3. The next day, he read another 30 pages, and the number of pages he had not read was this one
The total number of pages in the book was $30+30=60$pages. The number of pages read is $2x$, and the number of unread pages is $3x$. where $x$is an integral number. On the first day, the ratio of pages read to unread was $2:3, so $2x=3x+30. The solution is $x=10$. Therefore, the number of pages read is $2x=20$, and the number of unread pages is $3x=30$. So this novel has a total of $60$pages, I've read $20$pages, I haven't read $30$pages.
Xiao Ming read a book. On the first day, he read 10% of the book, the second day, he read 35%, and the third day, he read 44 pages. This book…
How many pages are there in this book? According to the title, Xiaoming read 10% of the book on the first day, which was 10% of the book divided by 100% = 1/10 pages. Xiao Ming read 35% of the book the next day, which was 35% of the book divided by 100% = 035 pages. Xiao Ming read 44 pages of the book on the third day, so the number of pages in the book can be calculated by the following formula: 1 ÷ (1/10 + 035 + 1/10) = 44 Solve the equation: Number of pages in the book = 44 × 100%/(1 + 035 + 1) = 3520 Therefore, this book had a total of 3520 pages.
Will you get diarrhea if you lie down and read novels after eating every day?
Lying down and reading novels after eating every day might cause diarrhea. After eating, the digestive system needs to digest and absorb food so that the body can obtain nutrients. If you lie down immediately, your body will relax, which will reduce the burden on your digestive system, which will slow down your digestive function and easily cause diarrhea. Therefore, it is recommended to rest for a while after a meal and wait for the body to relax before lying down to read a novel to avoid diarrhea.
Xiaodong read a book. On the first day, he read 3/5 of the book, and the next day he read 20 pages. At this time, he had read the number of pages in the book.
Xiao Dong read 3/5 of the book on the first day, which was 0.6 times the volume of the book. The next day, he read another 20 pages, which was equivalent to 1/5 of the entire book, which was 0.2 times the volume of the entire book. Therefore, the number of pages Little Dong had read was: The number of pages read = the volume of the book x the number of days read-the total number of pages = 06 × volume of the book × 1 - 02 × volume of the book = 02 × the volume of the book Since the total number of pages in the book did not change, the number of pages that Xiao Dong had read was 0.2 times that of the book.
Xiao Gang read a story book. On the first day, he read one-fifth of the book, and on the second day, he read 40% of the book.
As a fan of online literature, I can provide you with the following information about this book: Reading one-fifth of the book on the first day and then reading 40% of the book on the second day meant reading 40% of the book on the second day instead of 5/1 = 20% of 40%. Therefore, Xiao Gang had read 15% and 20% of the book on the first and second day. He still had 75% of the book left. If Xiao Gang wanted to finish reading the book, he would need to continue reading until he reached 75% of the book.
Lin Yun read a 156-page literary work. On the first day, he read 4/9 of the book. On the second day, he read 15/16 of the first day. On the second day, Lin Yun read...
Lin Yun read a 156-page literary work. On the first day, he read 4/9 of the book. On the second day, he read 15/16 of the first day. Lin Yun read it on the second day. Assuming that the book had a total of n pages, Lin Yun read 4/9 of the book on the first day (i.e. 4/9 * n), which meant that he read page n of the book. Next, Lin Yun read 15/16 of the number of pages he read on the first day (4/9 * n * 15/16), which meant that he read page n+1. Thus, the number of pages Lin Yun read on the second day was:(15/16) * (4/9 * n + 1) = 15/16 * (n + 4/9 * n). Since n+4/9*n is an integral number, 15/16 * (n + 4/9*n) must be a multiple of 15. Thus, when n was a multiple of 15, the number of pages Lin Yun read on the second day was 15/16 * (n + 4/9*n), which was a multiple of 15. For example, when n is 30, the number of pages Lin Yun reads on the second day is 15/16 *(30 + 4/9 * 25) = 15/16 *(30 + 10/9 * 25) = 15/16 * (35 + 5/18) = 15/16 * (35 + 25/18) = 15/16 * (375 + 125/18) = 15/16 * (375 + 625) = 15/16 * 37 = 45 When n was 15, the number of pages Lin Yun read on the second day was 15/16 * (15 + 4/9 * 15) = 15/16 * (15 + 10/18) = 15/16 * (15 + 5/6) = 15/16 * 20 = 375. When n was 20, the number of pages Lin Yun read on the second day was 15/16 * (20 + 4/9 * 20) = 15/16 * (20 + 10/18) = 15/16 * (20 + 5/6) = 15/16 * 375 = 45. Thus, Lin Yun read a 156-page literary work on the first day and read 4/9 of the book (4/9 * 156). On the second day, he read 15/16 of the first day (4/9 * 156 * 16/15). On the second day, he read 15/16 * (156 + 4/9 * 156).
He had read 12 pages on the first day, 6 more pages on the next day, and 48 pages on the last day. How many days had he read?
After reading 12 pages on the first day, he read 6 more pages every day than the previous day. On the last day, he read 48 pages. How many days did he read in total? He had read $12+12 + 12 + 12 + 12 +12+6+48$in total. Reading 6 more pages a day than the day before, so obviously in the first week, I read $12+12 + 12 + 12 + 12 +12+6+12=55$days. In the second week, he read $12+12 + 12 + 12 + 12 +12+6+12+12=63$days. By analogy, we can know that the total amount of reading before the end of the book is $55+63+70+73+80+86+98+48=695$days. Therefore, he read for a total of seven days.
Xiaodong read a book. On the first day, he read one-fifth of the book, and on the second day, he read 15 pages. In this way, he read the whole book in two days
Xiao Dong read a fifth of the book on the first day and 15 pages on the second day. In two days, he read 15 times the book. Therefore, he had read the entire book in two days, 3/2 = 15 times. Then the book had a total of $pages × 15 = (pages + 15)+2 $pages.
If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.
Xiaoming reads a novel. If he reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day. Based on this information, we can formulate the following equation: Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day. Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions: Xiaoming finished reading the novel before the stipulated date 2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days Therefore, we can write the following equation: x/35 = (x/12) - 1 Solve the equation: x = 35x/12 + 1 = 40 Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
Little Light read a story book. On the first day, he read a quarter of the book, and on the second day, he read a fifth of the book. On the first day, he read 10 more pages than the second day.
If the total number of pages in the storybook was X, then Little Light would read a quarter of the book on the first day, which was X/4 pages, and a fifth of the book on the second day, which was X/5 pages. According to the topic, the first day was 10 pages more than the second day, so there were: (X/4 - X/5) = 10 To simplify it: X/10 = 10 X = 100 Therefore, the total number of pages in the storybook was 100. Little Light read 100/4 = 25 pages on the first day and 100/5 = 20 pages on the second day. He read 45 pages in total.
