Problem Analysis

We are given that 8 identical erasers cost 24 rubles. We need to determine how many identical notebooks can be purchased for the same amount if 3 notebooks cost the same as 4 of those erasers. We need to solve this problem using a maximum of two operations.

Solution

Let's break down the problem step by step:

1. We know that 8 identical erasers cost 24 rubles. To find the cost of one eraser, we can divide the total cost by the number of erasers: 24 rubles / 8 erasers = 3 rubles per eraser.

2. We are also given that 3 notebooks cost the same as 4 erasers. Let's find the cost of one notebook. Since 4 erasers cost 12 rubles (4 erasers * 3 rubles per eraser = 12 rubles), we can divide the cost by the number of notebooks: 12 rubles / 3 notebooks = 4 rubles per notebook.

3. Now, we need to determine how many notebooks can be purchased for 24 rubles. To do this, we divide the total amount by the cost of one notebook: 24 rubles / 4 rubles per notebook = 6 notebooks.

Therefore, you can buy 6 identical notebooks for 24 rubles.

Answer

You can buy 6 identical notebooks for 24 rubles.
