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.
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.
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.
Xiao Ming read a mini-novel in three days. On the first day, he read more than 6 pages of the book. On the second day, he read half of the book. On the third day, he read 2 pages of the first day.
Xiao Ming read a mini-novel in three days. On the first day, he read more than a quarter of the entire book and six pages. On the second day, he read half of the entire book. On the third day, he read twice as many pages as the first day. According to the description of the title, Xiaoming read 1/4 of the book on the first day, which was 1/4 + 6/100 = 17/100 = 1/5. Therefore, Xiao Ming read about one-fifth of the book on the first day. The next day, Xiao Ming read half of the book. Therefore, Xiao Ming read 1/2 × 1/2 = 1/4 of the book the next day. On the third day, Xiao Ming read twice the number of the first day, which was 1/5 × 2 = 4/15. Therefore, Xiao Ming read about 4/15 of the book on the third day. As Xiao Ming read for a total of 3 days, the total number of pages in the book is: Total pages = Day 1 pages + Day 2 pages + Day 3 pages = 1/5 + 1/4 + 4/15 = 9/10 Therefore, the total number of pages in the novel was nine.
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.
Little Wang read a book. On the first day, he read 12.5% of the whole book. On the second day, he read 136 pages. The ratio of the remaining pages to the number of pages he had read was 3:5...
Let the total number of pages of the book be x, then Xiaowang read 125% on the first day = 0125x 136 pages on the second day, so Xiaowang read a total of 0125x + 136 pages. The ratio of the remaining pages to the number of pages seen is 3:5, so the number of pages left is 0875x- 136, and the number of pages seen is 0875x- 136 + 0125x = 09x. According to the question, the ratio of the remaining pages to the number of pages seen is 3:5, so the equation can be written: 0875x - 136 = 3(09x) Solve the equation: 0125x = 192 x = 144 Therefore, the total number of pages in this book was 144.
When you read a book, you read one-fifth of the book on the first day, and you read one-fourth of the book on the second day, and you read 30 more pages on the first day than the second day.
Assuming that the book has $x$pages, reading one-fifth of the book on the first day means reading $/frac{1}{5}x$pages, then reading one-quarter of the book on the second day means reading $/frac{1}{4}x$pages. According to the fact that we read 30 more pages on the first day than the second day, we can write the equation: $$ \frac{1}{5}x - \frac{1}{4}x = 30 $$ By solving this equation, one could obtain: $$ x = 150 $$ So this book has 150 pages.
Xiao Ming read a book. On the first day, he read 1/6 of the book, the second day, he read 24 pages, and the third day, he read the total number of pages in the previous two days.
Xiao Ming read a book on the first day, he read 1/6 of the whole book, the second day, he read 24 pages, the third day, he read the total number of pages in the previous two days If he read 24 pages the next day, he would read (24 div6) = 4 pages the next day. The rest of the books had 5/6 pages. Xiaoming read 1/6 pages on the first day, so he read (5/6 div1/6) = 30 pages on the first day. Xiao Ming's remaining book had 1/6 pages. The number of pages he read the next day was 4 + 30 = 34. Xiao Ming's remaining book had 1/6 pages. The number of pages he read on the third day was 34 + 24 = 58. Therefore, on the third day, Xiao Ming read the entire book's 58 + 6 = 9 pages.
Naughty read a storybook. On the first day, he read 40% of the total pages. On the second day, he read 24 pages less than the first day. There were still 56 pages left. This book…
The total number of pages in this book is 100 pages. On the first day, I read 40 pages. On the second day, I read 24 pages less than the first day. Therefore, the number of pages I read on the second day is the number of pages I read on the first day plus 24 pages. The next day, he read 40 + 24 = 64 pages. So the total number of pages in the book was 100. Naughty read 40 pages on the first day and 64 pages on the second day. The remaining pages were 100 - 64 = 36 pages. On the first day, Naughty had read 40% of it, which was four pages. The next day, he read page 64/4 = 14. Therefore, the number of pages left for Naughty was 36 - 14 = 22. So, in the end, Naughty finished reading 22 pages, which was four pages less than the first day.
Little Light read a book. On the first day, he read six pages. After that, he read four more pages every day. On the third day, he read two-fifths of the book and continued to read.
Xiao Hua reads a book on the first day, reads six pages, then reads four more pages every day, and on the third day, he reads two-fifths of the book. According to the question description, Little Light read four more pages every day than the previous day, so the total number of pages per day was the total number of pages on the previous day plus four pages. Therefore, after Little Light read six pages on the first day, the number of pages he read every day was the number of pages from the previous day plus four pages, which was six pages + four pages = ten pages. From the second day onwards, Little Light read four more pages a day than the previous day. Therefore, the number of pages he read every day was the number of pages from the previous day plus four pages, which was 10 pages + 4 pages + 4 pages = 16 pages. By analogy, we can find that when Little Light reads to the n-th day, the number of pages Little Light reads every day is the number of pages from the previous day plus 4 pages, which is n-pages + 4 pages. Therefore, by the third day, Little Light had read 2/5 of the book, which was 32 pages + 4 pages = 36 pages. Therefore, after the third day, Little Light still had 16 pages left to read. The total number of pages in the book was 36, so Little Light needed to read another 16 pages to finish reading.
Xiao Lin read a book. On the first day, he read 1/5 of the book. On the second day, he read 4/9 of the book. At this time, there were still 32 pages left.
Kobayashi read 1/5 of the book on the first day and 4/9 on the second day. The remaining pages were: 32 pages/(1 - 1/5) - 32 pages = 32 - 32 pages/4/9 = 32 - 48 pages/1/5 Next, Kobayashi needed to convert the remaining pages into whole pages and calculate: 32 - 48 pages/1/5 = 160 - 192 pages/4/9 = 160 - 384 pages/5 Since the number of pages and the number of pages were both whole numbers, the final result should be 160 - 384 = 112 pages. Therefore, Kobayashi had already read 1/5 + 4/9 of the book before the next day, which was 11/45. The remaining pages were 32 pages. Kobayashi needed to finish these 32 pages by the next day to finish the book.
