Answer 2

Problem Analysis

We are given that there were 40 notebooks in a kiosk, and a certain fraction of them were sold for the day. We need to determine how many notebooks were sold.

Solution

Let's break down the information given: - Out of all the notebooks, three-eighths were sold in the "клетка" (cell). - Additionally, two-fifths were sold in the "линейка" (line).

To find the number of notebooks sold in the "клетка," we can calculate three-eighths of the total number of notebooks. Similarly, to find the number of notebooks sold in the "линейка," we can calculate two-fifths of the total number of notebooks.

Let's calculate the number of notebooks sold in the "клетка" and the "линейка."

Calculation

Number of notebooks sold in the "клетка": ``` (3/8) * 40 = 15 ```

Number of notebooks sold in the "линейка": ``` (2/5) * 40 = 16 ```

Answer

Therefore, 15 notebooks were sold in the "клетка" and 16 notebooks were sold in the "линейка" for the day.
