Problem Statement

Рыбаки ловили первые 3 дня недели по 100 ц рыбы в день, а следующие 3 дня по 20 ц в день. Сколько всего кг рыбы поймали рыбаки за 6 дней? Решите задачу двумя способами.

Solution 1: Using Centners and Kilograms

To solve this problem, we can convert the given quantities from centners to kilograms and then calculate the total weight of fish caught by the fishermen.

1. First 3 days: 100 centners per day - 1 centner = 100 kilograms - So, for the first 3 days, the fishermen caught 100 centners/day * 100 kilograms/centner = 10,000 kilograms of fish.

2. Next 3 days: 20 centners per day - Similarly, for the next 3 days, the fishermen caught 20 centners/day * 100 kilograms/centner = 2,000 kilograms of fish.

3. Total weight of fish caught in 6 days: - Adding the weights from the first 3 days and the next 3 days, we get: 10,000 kilograms + 2,000 kilograms = 12,000 kilograms of fish.

Therefore, the fishermen caught a total of 12,000 kilograms of fish in 6 days.

Solution 2: Using Centners Only

Alternatively, we can solve the problem by directly calculating the total weight of fish caught in centners and then converting it to kilograms.

1. First 3 days: 100 centners per day - For the first 3 days, the fishermen caught 100 centners/day.

2. Next 3 days: 20 centners per day - For the next 3 days, the fishermen caught 20 centners/day.

3. Total weight of fish caught in 6 days: - Adding the weights from the first 3 days and the next 3 days, we get: 100 centners/day * 3 days + 20 centners/day * 3 days = 300 centners + 60 centners = 360 centners.

4. Converting centners to kilograms: - 1 centner = 100 kilograms - So, 360 centners = 360 centners * 100 kilograms/centner = 36,000 kilograms of fish.

Therefore, the fishermen caught a total of 36,000 kilograms of fish in 6 days
