Lanlan and Naughty, reading the same book. This book has a total of 90 pages. I've already read two-thirds of it. Naughty has read the same number of pages.
If Lan Lan and Naughty had read two-thirds of the book, then Naughty would have read 30 pages. The remaining pages were $90 - 30 = 60$pages. Therefore, Lan Lan still needed to read $60$pages. So they still needed to look at the $40$page and the $20$page.
Naughty has read more than one-fifth of the total number of pages in a book. Twenty-four pages and the remaining two-thirds of the total number of pages. How many pages are there?
Let's assume that the total number of pages in this book is x. The number of pages that Naughty had already read was x +5 + 24, which was a total of x +5+24. The remaining pages make up two-thirds of the total number of pages, so there are: x÷5+24 + x/2 = x The above formula was simplified: x/2 + 24 = x After the reduction, it was obtained: x/2 = 24 Solution: x = 48 Therefore, the total number of pages in this book was 48.
Naughty reads a book with a total of 170 pages. He has already read 90 pages. How many pages does he read on average every day?
Naughty had read 90% of the 170 pages of the book, which meant that Naughty had read 90/19=5267 pages. The average number of pages to read in the remaining four days can be calculated by dividing the total number of pages by the number of days. 170 pages/4 days =45 pages/day. So, on average, Piao Jiao would read 45 pages a day.
Xiaofang has read a book and has read 3/5 of the book. What is the ratio of the remaining pages to the total number?
Xiaofang had already read three-fifths of the book, so the remaining pages were the total number: Remaining pages/total = (1 - 3/5)/total = 2/5 Therefore, the ratio of the remaining pages to the total number was 2/5:1 = 4:5.
Xiao Ming has a book with a total of 240 pages. He has already read two-fifths of the book. How many pages are left?]
Xiao Ming had a book with a total of 240 pages and had already read two-fifths of the entire book, so he had already read 240 × 2/5 = 96 pages. Therefore, there were still 240 - 96 = 144 pages left.
Three fifths of a book has been read, and there are 15 pages left. The number of pages read is a fraction of the number of pages not read
If a book has been read three-fifths of the way and there are 15 pages left, then the number of pages read is the number of pages not read: Number of pages seen/number of pages not seen = 3/5/4/5 = 3/4 Therefore, the number of pages that had been read was four-thirds of the number of pages that had not been read.
How many pages did he read when he read two-thirds of the 170 pages of the book?
The book had a total of 170 pages. Two-thirds of it was equivalent to 70 pages. The remaining three-quarters were equivalent to 40 pages. Therefore, he had read 170 pages in total, and he needed to read the remaining 40 pages twice, which was 70 pages.
A book has a total of 150 pages, and Xiao Ming has already read 54 pages. The remaining pages are 8 pages a day, and it will take him a few days to finish them.
Xiao Ming had already read 54 pages and was reading 8 pages a day. Therefore, he still needed 8 × 7 = 56 days to finish reading the remaining pages.
Xiaoming reads a book on the first day, reading 20% of the total number of pages, the number of pages read on the second day and the number of pages read on the first day is 5:4
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.
Xiao Ming is reading an extra-cursory book. This book has 150 pages. He has read three-fifths of the total pages. How many pages has he read and how many pages are left?
The total number of pages that Xiao Ming had read was 150. He had already read three-fifths of the total number of pages, which was 3/5 = 6%. Therefore, Xiao Ming had already read about 6% of the pages, and the remaining pages were 150 - 6%= 144 pages.
Dongdong was reading a book with a total of 150 pages. At the end of the second week, he found that the number of pages he had not read was exactly the same as the number of pages he had read in the first week.
Dongdong read a total of x pages at the end of the first week. The total number of pages in this book is 150, so: At the end of the second week, Dongdong had read (150 - x) pages. Dongdong hadn't finished reading 150 pages by the end of the second week, so he had read (150 - x) pages less than or equal to 150 pages. And because Dongdong had read page X in the first week: x = 150 - x + 1 = 149 The solution was x = 1, so Dongdong read a total of 149 pages in the first week. Dongdong had read (150 - 1) = 149 pages by the end of the second week. Therefore, Dongdong read a total of 149 pages in this book, and there was still one page left at the end of the second week.
