Suppose the book has x pages. On the first day, he read a quarter of the book, which was 1/4 * x page of the book. The next day, he read two-fifths of the book, which was 1/4 * x pages, 2/5 = 5/16 * x pages. There were still 14 pages left, so: 14 ÷ (5/16 * x - 1/4 * x) = 14/(1/4 * x - 1/4 * x) = 14/(1/16 * x - 1/16 * x) = 14/(5/8 * x) = 14/(1/8 * x) To simplify it: 14/(1/8 * x) = 14 So 8 * 14 = x Solution:x = 96 So this book had a total of 96 pages.

Let the total number of pages in this book be x pages. Reading 20% of the book on the first day meant reading 20% * x pages, which was 02x pages. The next day, he read 25% of the total number of pages, which meant that he read 25% * x pages, which was 025x pages. There were 110 pages left. According to the above calculation, the equation can be listed: 02x + 025x + 110 = x Solve this equation: 3x = 110 x = 33 Therefore, the total number of pages in this book was 33.

Suppose the book has x pages. On the first day, he read two-fifths of the book, which was 2/5x pages. The next day, he read a quarter of the book, which was x/4 pages. Because there were still 70 pages left, there were: 2/5x + x/4 - 70 = 0 To simplify it: 5x/4 - 70 = 0 Solution: x = 400 Therefore, the book had a total of 400 pages.

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.

How many pages were there in this storybook? If Xiaoling had read 1/5 of the book on the first day and 30 pages on the second day, there would still be 3/4 of the book left?

If the book has x pages: I read 1/5x page on the first day I read (5/6)x pages the next day, where 5/6x means that the number of pages read on the first day accounts for 5/6 of the number of pages read on the second day. The remaining pages are x - 1/5x - (5/6)x = 66 pages According to the above equations, a set of linear equations with two variables can be listed: 1/5x + (5/6)x = 66 Solution:x = 460 Therefore, the book had 460 pages.

This novel has a total of $42$pages. Let the total number of pages in this novel be $x$pages: On the first day, he read four-sevenths of the book, which was $/frac{4}{7}x$pages. The next day, he read the remaining three-fifths of the book, which was $/frac{3}{5}x$pages. Because there are still $42$pages to read, there are: $$\frac{4}{7}x + \frac{3}{5}x = 42$$ To simplify it: $$x = 350$$ Therefore, the novel had a total of $350$pages.

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.

A book had 72 pages. Xiao Ming had read two-ninths of the book on the first day and one-third of the book on the second day. How many pages were left?

1 answer

2024-09-18 15:35

The remaining pages were:72 pages- 2 × 2/9 = 72 pages-1/3 = 66 pages. This was because Little Ming had read two-ninths of the page on the first day, which was 24 pages. The next day, he read a third of the book, which was 12 pages. Therefore, the remaining pages were the total number of pages minus the number of pages that had been read, which was 72 pages- 24 pages + 12 pages = 66 pages.
