Answer 1

Надо
1.) 20/(5-1)=5(тетрадей)-1 часть и 1-ая  пачка 
2.)5*5=25(тетрадей)-во 2-ой пачке

Answer 2

Problem Analysis

Kolya noticed that there are 5 times fewer notebooks in the first pack compared to the second pack. Olga said that there are 20 fewer notebooks in her pack compared to the second pack. We need to determine the number of notebooks in each pack.

Solution

Let's assume that the number of notebooks in the second pack is x. According to Kolya, the number of notebooks in the first pack is 5 times less than the second pack, so it would be x/5. According to Olga, the number of notebooks in her pack is 20 less than the second pack, so it would be x - 20.

To find the number of notebooks in each pack, we can set up the following equation:

x/5 = x - 20

To solve this equation, we can multiply both sides by 5 to eliminate the fraction:

x = 5(x - 20)

Expanding the equation:

x = 5x - 100

Rearranging the equation:

4x = 100

Dividing both sides by 4:

x = 25

Therefore, there are 25 notebooks in the second pack.

To find the number of notebooks in the first pack, we can substitute the value of x into either of the equations:

First pack: x/5 = 25/5 = 5

Therefore, there are 5 notebooks in the first pack.

Answer

There are 5 notebooks in the first pack and 25 notebooks in the second pack.
