Question

Девочки решили прочитать приключенческий роман и обменятся впечетлениями. Они взяли в библиотеке три одинаковых книги . Через неделю выяснилось, что Таня прочитала 5/9 книги, Оксана 7/12 книги, а Ира 6/11 книги. Кому из них меньше осталось прочитать и сколько страниц осталось если в книге 792 страницы?

Answer 1

Сначала нужно 5/9, 7/12 и 6/11 привести к общему знаменателю.
Общий знаменатель будет 396.
5/9=44/396
7/12=33/396
6/11=36/396
Значит больше всех прочитала Таня и ей осталось прочитать 352 страницы.

Answer 2

To find out who has less left to read and how many pages are left, we need to calculate the number of pages each girl has left to read.

Let's start with Tanya. Tanya has read 5/9 of the book, which means she has 4/9 left to read. To find out how many pages she has left, we can multiply the total number of pages in the book by the fraction of the book she has left to read:

Pages left for Tanya = (4/9) * 792

Next, let's calculate the number of pages left for Oksana. Oksana has read 7/12 of the book, which means she has 5/12 left to read. We can use the same formula to find out how many pages she has left:

Pages left for Oksana = (5/12) * 792

Finally, let's calculate the number of pages left for Ira. Ira has read 6/11 of the book, which means she has 5/11 left to read. Again, we can use the formula to find out how many pages she has left:

Pages left for Ira = (5/11) * 792

Now, let's calculate the actual values:

Pages left for Tanya = (4/9) * 792 = 352 pages Pages left for Oksana = (5/12) * 792 = 330 pages Pages left for Ira = (5/11) * 792 = 360 pages

Therefore, Tanya has the least number of pages left to read, with 352 pages remaining.
