Problem Analysis

Алёша and his father caught a total of 37 fish during their fishing trip. The types of fish they caught were bream, perch, and roach. It is given that the number of perch was 5 times more than the number of bream, and the number of roach was 9 more than the number of bream. We need to determine the number of bream, perch, and roach that Алёша and his father caught.

Solution

Let's assume the number of bream caught is x. According to the problem, the number of perch caught is 5 times more than the number of bream, which means the number of perch is 5x. Similarly, the number of roach is 9 more than the number of bream, which means the number of roach is x + 9.

We know that the total number of fish caught is 37. So, we can write the equation:

x + 5x + (x + 9) = 37

Simplifying the equation:

7x + 9 = 37

Subtracting 9 from both sides:

7x = 28

Dividing both sides by 7:

x = 4

Therefore, Алёша and his father caught 4 bream, 5 times more perch (4 * 5 = 20), and 9 more roach (4 + 9 = 13).

Answer

Алёша and his father caught: - 4 bream - 20 perch - 13 roach
