Congcong read 1/5 of the book on the first day. The number of pages he read the next day was equivalent to 1 of the entire book because there were 360 pages in the entire book. The number of pages he read the next day was 360 + 1 = 360. Therefore, the number of pages that Congcong read the next day was 1/1 of the entire book, which was 1/1 = 1.

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.

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.

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 Ming read 20% of the total number of pages on the first day of reading a book, which means that the total number of pages multiplied by 20% equals 20% of the total number of pages. On the second day, the ratio of pages read on the first day was 5:4, which meant that half of the total pages read on the second day was 25% of the total pages. Therefore, Xiao Ming read the total number of pages multiplied by 25% the next day, which was equal to the total number of pages multiplied by 5%. Divide the total number of pages by 5 to get the number of pages that Xiaoming read the next day divided by 5. That is, the total number of pages divided by 5 multiplied by 40% equals the total number of pages multiplied by 10%. Therefore, Xiao Ming read the total number of pages multiplied by 10% the next day, which was equal to the total number of pages multiplied by 5.
