Answer 1

а) 1)120*5=6000(руб)

б) 6000:120=5(руб)

Answer 2

Решение.
Пусть блокнот стоит - x руб., тогда книга стоит - 5x рублей. Из условия известно, что за покупку заплатили 120 руб. Составим уравнение:
x+5x=120
6x=120
x=120÷6
x=20(руб.) - цена блокнота
120-20=100(руб.) - цена книги
100÷20=5(блокнотов) - можно купить за деньги, что потрачено на 1 книжку
120÷20=6(блокнотов) - можно купить за 120 руб.

Answer 3

Given Information:

- The total amount paid for a notebook and a book is 120 rubles. - The book is 5 times more expensive than the notebook.

Calculating the Prices:

Let's assume the price of the notebook is x rubles. Since the book is 5 times more expensive than the notebook, the price of the book would be 5x rubles.

According to the given information, the total amount paid for the notebook and the book is 120 rubles. We can set up the following equation to solve for the prices:

x + 5x = 120

Simplifying the equation, we have:

6x = 120

Dividing both sides of the equation by 6, we find:

x = 20

Therefore, the price of the notebook is 20 rubles, and the price of the book is 5 times that, which is 100 rubles.

Number of Notebooks that can be Purchased with the Same Amount Spent on a Book:

Since the price of the notebook is 20 rubles and the amount spent on a book is 100 rubles, we can calculate the number of notebooks that can be purchased with the same amount by dividing the amount spent on the book by the price of the notebook:

Number of notebooks = Amount spent on book / Price of notebook = 100 rubles / 20 rubles = 5 notebooks

Therefore, with the same amount spent on a book, you can buy 5 notebooks.

Total Number of Notebooks that can be Purchased with 120 Rubles:

To calculate the total number of notebooks that can be purchased with 120 rubles, we divide the total amount by the price of the notebook:

Total number of notebooks = Total amount / Price of notebook = 120 rubles / 20 rubles = 6 notebooks

Therefore, with 120 rubles, you can buy 6 notebooks.

Price of the Notebook:

As calculated earlier, the price of the notebook is 20 rubles.

In summary: - The price of the notebook is 20 rubles. - The price of the book is 100 rubles. - With the same amount spent on a book (100 rubles), you can buy 5 notebooks. - With 120 rubles, you can buy 6 notebooks.
