Xiao Xiao was reading a 150-page book. She had already read two-fifths of the book. How many pages were left?

Huanhuan has already finished reading three-fifths of the total number of pages in the storybook. There are still 36 pages left. How many pages are there in this storybook?
The number of pages in a storybook can be expressed as $x$, so the total number of pages is $x \times 3/5$. Since there were still 36 pages to read, the total number of pages in the storybook plus these 36 pages was $x/times 3/5 + 36$. And because the book had a total of $x$pages, the equation could be listed: $$x \times 3/5 + 36 = x$$ If you solve this equation, you get $x=300$. Therefore, the story book had a total of $300$pages.
Xiao Hong had already read 40 pages of the book, which was exactly two-fifths of the book. How many pages were left?
If Xiao Hong had already read 40 pages of a book, which was two-fifths of the book, then Xiao Hong had already read 20% or 0.2 times the book. How many pages are there in the book? You can divide the number of pages by the number of pages in the book: (100% - 02) / 100% = 90% Therefore, Little Red only had 10 pages left.
Naughty was reading a storybook. He had already read 5/7 of the total number of pages. There were still 40 pages left. How many pages were there in this storybook?
Let's say this storybook has a total of $x$pages. Naughty had finished reading $5/7$of the total page count, which meant that he had $2/7$left. Therefore, Naughty still needed to read $40$to finish the total number of pages. According to the meaning of the question, mischievous still needs to look at $40$pages, so $x - 40$should be divided by $7$. Since $x$is the total number of pages,$x$should be greater than or equal to $40$. Therefore, we can write an equation: $$x \geq 40 + 40 \times 7 = 560$$ The solution to this equation is $x=567$. So this story book had a total of $567$pages.
A storybook has 200 pages. Xiao Ming read two-fifths of it on the first day and 15% on the second day. How many pages are left?
Xiao Ming read two-fifths of the page on the first day. The next day, he read 15%, which was page 015. Therefore, the remaining pages were 200 - (2/5 + 015) = 200 - 045 = 19545 pages. Therefore, Little Ming still had 19545 pages left.
