Answer 1

1 способ:
1) 1 - (5/7) = 2/7 (кн.) 
2) 140*(2/7) = 40 (стр.) 
2 способ 
1) 140*(5/7) = 100 (стр.)
2) 140 - 100 = 40 (стр.)

Answer 2

1) 1 - ( 5/7 ) = 2/7 ( книги ) осталось прочитать
2) 140 * ( 2/7 ) = 40 ( страниц ) осталось прочитать
2 способ
1) 140 * ( 5/7 ) = 100 ( страниц ) прочитал
2) 140 - 100 = 40 ( страниц ) осталось прочитать

Answer 3

Question 1: "Миша читает книгу, в которой 140 страниц, и прочитал 5 седьмой всей книги. Сколько страниц ему осталось прочитать?"

To answer this question, we need to determine how many pages Misha has left to read. We know that the book has 140 pages and Misha has already read 5/7 of the entire book.

To find the number of pages Misha has left to read, we can subtract the number of pages he has already read from the total number of pages in the book.

Let's calculate it: - Total number of pages in the book: 140 - Number of pages Misha has already read: 5/7 * 140 = 100

Therefore, Misha has 40 pages left to read.

Question 2: "Решение какой задачи задания N170 поможет тебе ответить на вопрос данной задачи?"

To determine which problem-solving technique or concept will help us answer the question, we need more information about task N170. Unfortunately, the search results do not provide any relevant information about task N170 or its content. Without further details, it is not possible to identify which specific problem-solving technique or concept would be applicable to this question.

Question 3: "Реши задачу."

As mentioned earlier, the solution to the problem is that Misha has 40 pages left to read.

Question 4: "Найди другой способ решения задачи."

Another way to solve this problem is by calculating the fraction of the book that Misha has already read and then subtracting it from 1 to find the fraction of the book that he still needs to read.

Let's calculate it: - Fraction of the book that Misha has already read: 5/7 - Fraction of the book that Misha still needs to read: 1 - 5/7 = 2/7

To find the number of pages Misha has left to read, we can multiply the fraction of the book he still needs to read by the total number of pages in the book.

Let's calculate it: - Total number of pages in the book: 140 - Fraction of the book Misha still needs to read: 2/7 - Number of pages Misha has left to read: (2/7) * 140 = 40

Therefore, using this alternative method, we also find that Misha has 40 pages left to read.

I hope this helps! Let me know if you have any further questions.
