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.
A book has a page, read 15 pages a day, and finish it in a week
A book has a page A. Reading 15 pages a day in a week is just enough. Assuming a book has page A and 15 pages a day, the number of days needed to finish the book in a week is: a ÷ 15 = (a + a) ÷ 2 = 2a / 2 + a / 2 Transferring items can be sorted out: 2a / 2 = a + a / 2 To simplify it: a = 4 Therefore, a book had four pages, and 15 pages a day was just enough to finish it in a week.

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.

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.
