Answer 1

1) 2 3/5 + 1 1/5 = 13/5 + 6/5 = 19/5 = 3 4/5 (кг) = 3кг 800г - сыновья вместе ,
2) 7 - 3 4/5 = 35/5 - 19/5 = 16/5 = 3 1/5 (кг) = 3кг 200г.
Ответ : отец поймал 3кг 200 г рыбы

Answer 2

Старший сын  - 2 3/5  кг 
Младший сын - 1 1/5 кг
Отец - ?
Всего - 7 кг 
1) 2 3/5 + 1 1/5 = 13/5 +6/5 = 19/5= 3 4/5 (кг) поймали сыновья вместе
2) 7 - 3 4/5 = 3 1/5 кг  = 3 кг 200 г - поймал отец 
(т.к. в 1 кг = 1000 г  ⇒ 1000:5 *1 = 200 г. - это 1 часть из 5 (1/5) )
Ответ 3 кг 200 г рыбы поймал отец

Answer 3

Problem Analysis

We are given that a father and his two sons went fishing and caught a total of 7 kg of fish. The older son caught 2 3/5 kg of fish, the younger son caught 1 1/5 kg of fish, and the father caught the rest. We need to determine how much fish the father caught in kilograms and grams.

Solution

To find the weight of fish caught by the father, we need to subtract the weights caught by the two sons from the total weight of 7 kg.

Let's calculate the weight caught by the father step by step:

1. Convert the mixed fractions to improper fractions: - The weight caught by the older son is 2 3/5 kg, which can be written as (5 * 2 + 3) / 5 = 13/5 kg. - The weight caught by the younger son is 1 1/5 kg, which can be written as (5 * 1 + 1) / 5 = 6/5 kg.

2. Add the weights caught by the two sons: - The total weight caught by the sons is 13/5 + 6/5 = 19/5 kg.

3. Subtract the total weight caught by the sons from the total weight of 7 kg: - The weight caught by the father is 7 - 19/5 = 35/5 - 19/5 = 16/5 kg.

4. Convert the improper fraction to a mixed fraction: - The weight caught by the father is 16/5 kg, which can be written as 3 1/5 kg.

Therefore, the father caught 3 1/5 kg of fish.

To convert this weight to grams, we can multiply it by 1000 since there are 1000 grams in a kilogram:

3 1/5 kg = (3 + 1/5) kg = 3 kg + 1/5 kg = 3 kg + (1/5 * 1000) g = 3 kg + 200 g = 3,200 g.

Therefore, the father caught 3,200 grams of fish.

Answer

The father caught 3 1/5 kg (or 3,200 g) of fish.

Please note that the answer is based on the given information and calculations.
