Answer 1

Мы знаем то что Володя поймал 4 окуня и 3 леща . Нам задали вопрос ( сколько всего рыб ?).  Мы сможем ответить на этот вопрос одним действием.  4 плюс 3 равно 7.                                              ответ:7 рыб

Answer 2

Task Solution:

To find out how many fish Volodya caught in total, we can simply add the number of pikes and perches he caught.

Volodya caught 4 pikes and 3 perches.

Therefore, the total number of fish Volodya caught is 4 + 3 = 7.

Reverse Problems:

1. Reverse Problem 1: If Volodya caught a total of 7 fish and 4 of them were pikes, how many perches did he catch?

Solution: Let's denote the number of perches caught as x. We know that the total number of fish is 7, and the number of pikes is 4. Therefore, the number of perches can be found by subtracting the number of pikes from the total number of fish: ``` Total number of perches = Total number of fish - Number of pikes Total number of perches = 7 - 4 Total number of perches = 3 ```

So, Volodya caught 3 perches.

2. Reverse Problem 2: If Volodya caught a total of 7 fish and 3 of them were perches, how many pikes did he catch?

Solution: Let's denote the number of pikes caught as y. We know that the total number of fish is 7, and the number of perches is 3. Therefore, the number of pikes can be found by subtracting the number of perches from the total number of fish: ``` Total number of pikes = Total number of fish - Number of perches Total number of pikes = 7 - 3 Total number of pikes = 4 ```

So, Volodya caught 4 pikes.

Conclusion:

Volodya caught a total of 7 fish, consisting of 4 pikes and 3 perches.
