Answer 1

Ответ:

Пошаговое объяснение:

Всего = 120 орехов

Коля = ? орехов

Таня = ? орехов, в 2р < чем Коля

Всего = 176 страниц

Прочитала = ? страниц, в 3р < чем осталось

Answer 2

Problem 1: Коля и Таня рвали орехи в лесу

According to the problem, Kolya and Tanya collected a total of 120 nuts. Tanya collected half as many nuts as Kolya. We need to find out how many nuts each of them collected.

Let's assume that Kolya collected x nuts. Since Tanya collected half as many nuts as Kolya, she collected x/2 nuts.

According to the problem, the total number of nuts collected is 120. So we can write the equation:

x + x/2 = 120

To solve this equation, we can multiply both sides by 2 to eliminate the fraction:

2x + x = 240

Combining like terms:

3x = 240

Now, we can solve for x by dividing both sides by 3:

x = 240/3

x = 80

Therefore, Kolya collected 80 nuts and Tanya collected half as many, which is 80/2 = 40 nuts.

So, Kolya had 80 nuts and Tanya had 40 nuts.

Problem 2: Алина прочитала в 3 раза меньше страниц, чем ей осталось прочитать

According to the problem, Alina read three times fewer pages than the number of pages she had left to read. The total number of pages in the book is given as 176. We need to find out how many pages Alina read.

Let's assume that Alina had x pages left to read. According to the problem, she read three times fewer pages than that, which is x/3.

The total number of pages read can be calculated by subtracting the number of pages Alina had left to read from the total number of pages in the book:

Total number of pages read = Total number of pages - Pages left to read Total number of pages read = 176 - x

According to the problem, the number of pages read is equal to three times fewer pages than the number of pages left to read:

Total number of pages read = x/3

Setting up an equation:

176 - x = x/3

To solve this equation, we can multiply both sides by 3 to eliminate the fraction:

3(176 - x) = x

Distributing the 3:

528 - 3x = x

Adding 3x to both sides:

528 = 4x

Now, we can solve for x by dividing both sides by 4:

x = 528/4

x = 132

Therefore, Alina had 132 pages left to read, and she read three times fewer pages, which is 132/3 = 44 pages.

So, Alina read 44 pages.
