Answer 1

1)(12+24)/4=9
2 способ:
12/4+24/4=9
Ответ:обе книги можно прочитать за 9 дней

Answer 2

Problem Statement

В одной книге 12 страниц, а во второй - 24. За сколько дней можно прочитать обе книги, если ежедневно читать по 4 страницы?

Solution 1: Using Basic Arithmetic

To solve this problem, we can use basic arithmetic. Let's break it down step by step:

1. Calculate the total number of pages in both books: 12 + 24 = 36 pages. 2. Divide the total number of pages by the number of pages read per day: 36 / 4 = 9 days.

Therefore, it will take 9 days to read both books if you read 4 pages per day.

Solution 2: Using Algebraic Equation

Alternatively, we can solve this problem using an algebraic equation. Let's represent the number of days it takes to read both books as 'x'.

1. The number of pages read per day is 4, so the number of pages read in 'x' days is 4x. 2. The total number of pages in both books is 36. 3. Therefore, the equation becomes: 4x = 36.

To solve for 'x', we divide both sides of the equation by 4: x = 36 / 4 = 9.

Again, we find that it will take 9 days to read both books if you read 4 pages per day.

Note: Both solutions yield the same result, which is 9 days.

Conclusion

In conclusion, if you read 4 pages per day, it will take 9 days to read both books. This can be calculated using basic arithmetic or by solving an algebraic equation.
