Assuming the book has $x$pages: - $40$on the first day. - The next day, he read $40/times 2 = 80$pages. - On the third day, if you read $3/8$on $40$pages, you would read $10$pages. Because there was still $5/8 left, there was: $$ 40 + 80 + 10 = \boxed{120} $$ So this book has 120 pages.

If a book has 252 pages and has been read for 8 days and there are 12 pages left, then the total number of pages in the book is 252 - 12 = 240 pages. The number of pages he read every day should be 240/8 = 30 pages. Therefore, you should read 30 pages a day.

Let's say this storybook has a total of $x$pages. According to the topic, 30 pages per day meant $30/div2 = 15$per hour. Zhang Ming read $15$pages per hour in $3$days so he read $3/30 = 90$pages in total. The remaining pages are $8/5 of the book, so there are: $$ 90 - \frac{8}{5} = \frac{16}{5} $$ Because the question requires the number of pages in the book, you need to multiply this result by $x$pages to get: $$ x \times \frac{16}{5} = \frac{16}{5} \times x = 96 $$ Solve this equation to get $x = 56$. So this story book had a total of $56$pages.

According to the question, Cockroach read 5 days *20 pages/day =100 pages, and the remaining 15 pages of the book are equal to the total number of pages-100 pages that have been read, so the total number of pages is: 100 pages +15 pages =115 pages. The answer was page 115.

There was a total of $12/15 - 1/15 = 165$pages left in the storybook. After reading the remaining two-sevenths, the remaining pages were two-sevenths of the original number. Therefore, he still needed to look at $165/div2/7 = 105$. Therefore, there were still 60 pages left.

Xiao Ming reads a book. He reads 1/13 of the book every day. After 4 days, there are 90 pages left. How many pages are there in this book?

1 answer

2024-09-16 12:07

Assuming that the book has $x$pages, the number of pages that Xiaoming reads on the fourth day is $x$multiplied by $1/13$. Because Xiao Ming had read for 4 days, the number of pages he read plus the remaining pages equals the total number of pages: $$ x + (x \times 1/13) + 90 = x $$ To simplify it: $$ x \times 12 - x \times 1/13 + 90 = 0 $$ Solve this equation: $$ x = 130 $$ Therefore, the book had a total of 130 pages.

Xiao Hua read a book and read 15 pages a day. After reading for 4 days, he still had 2/5 of the book left. How many pages of this storybook had he not read?

Assuming that this storybook had $x$pages, then the number of pages Little Light read every day was $15/div4 = 375$pages. Little Light had already read $4$for days, so the remaining pages were $x - 4/375 = x - 1125$. Because the number of pages Little Light reads every day is fixed, the number of pages can be expressed as: $$x - 4 \times 375 = 375 \times 4 - 1125$$ The above formula was simplified to: $$x = 48$$ Therefore, there were still $48 - 1125 = 3675 pages of this storybook that he had not read.
