Answer 3

To find out how many napkins are in 9 rolls, we can use the concept of proportionality. If we assume that each roll contains the same number of napkins, then the number of napkins is directly proportional to the number of rolls.

Let's set up a proportion:

Number of napkins in 6 rolls / Number of rolls = Number of napkins in 9 rolls / 9

Let's call the number of napkins in each roll "x."

6x / 6 = 9x / 9

Now, we can simplify the equation:

x = x

So, the number of napkins in each roll remains the same. Since you mentioned that there are "В" (which I assume is the Cyrillic letter "B") napkins in each roll, it means the number of napkins is constant, and therefore, in 9 rolls, there are still "В" napkins in total.
