Problem Analysis

To solve this problem, we need to determine how many albums can be purchased for the same amount of money that was used to buy 6 identical notebooks. We are given that 2 albums cost the same as 3 notebooks. We need to find the number of albums that can be purchased for the same amount of money.

Solution

Let's break down the problem step by step:

1. We know that 6 identical notebooks cost 60 rubles. 2. We are also given that 2 albums cost the same as 3 notebooks. 3. We need to find the number of albums that can be purchased for the same amount of money.

To solve this, we can set up a proportion:

6 notebooks = 60 rubles 2 albums = 3 notebooks

Let's find the cost of 1 notebook: - Divide the cost of 6 notebooks (60 rubles) by 6 to find the cost of 1 notebook: 60 rubles / 6 notebooks = 10 rubles/notebook.

Now, let's find the cost of 1 album: - Since 2 albums cost the same as 3 notebooks, we can set up a proportion: 2 albums / 3 notebooks = x albums / 1 notebook. - Cross-multiply and solve for x: 2 albums * 1 notebook = 3 notebooks * x albums. - Simplify: 2 albums = 3x albums. - Divide both sides by 3: 2 albums / 3 = x albums. - Therefore, the cost of 1 album is 2/3 of the cost of 1 notebook: (2/3) * 10 rubles = 6.67 rubles/album.

Now, let's find the number of albums that can be purchased for 60 rubles: - Divide the total amount of money (60 rubles) by the cost of 1 album (6.67 rubles/album): 60 rubles / 6.67 rubles/album ≈ 9 albums.

Therefore, you can buy approximately 9 albums for the same amount of money that was used to buy 6 identical notebooks.

Answer

You can buy approximately 9 albums for the same amount of money that was used to buy 6 identical notebooks.
