Task Solution:

To solve the given problem, we can use the information that 2 notebooks cost the same as 3 notepads. We also know that one notebook costs 9 rubles.

Let's calculate the cost of 11 notebooks based on this information.

Step 1: Calculate the cost of 1 notepad. - Since 2 notebooks cost the same as 3 notepads, the cost of 1 notepad is calculated as follows: - 2 notebooks = 3 notepads - 1 notebook = 3/2 notepads - Cost of 1 notepad = Cost of 2 notebooks / 3/2 - Cost of 1 notepad = 9 * 2 / 3 - Cost of 1 notepad = 6 rubles Step 2: Calculate the cost of 11 notebooks. - Now that we know the cost of 1 notepad, we can calculate the cost of 11 notepads: - Cost of 11 notepads = Cost of 1 notepad * 11 - Cost of 11 notepads = 6 * 11 - Cost of 11 notepads = 66 rubles

Therefore, the cost of 11 notebooks is 66 rubles.
