Answer 3

Let's break down the calculations step by step:

1. 28560 kg + 78 ц 546 kg: To add these quantities, we need to convert the centners (ц) to kilograms. Since 1 centner is equal to 100 kilograms, we can rewrite the expression as follows: 28560 kg + (78 × 100 kg) + 546 kg = 28560 kg + 7800 kg + 546 kg = 36906 kg.

2. 9 га 8 м² - 74 а 24 м²: To subtract these areas, we need to convert the units to a common unit. Since 1 hectare (га) is equal to 10000 square meters (м²) and 1 are (а) is equal to 100 square meters, we can rewrite the expression as follows: 9 га 8 м² - (74 × 100 м² + 24 м²) = 9 га 8 м² - 7424 м² = 9 га 8 м² - 7424 м² = (9 × 10000 м² + 8 м²) - 7424 м² = 90000 м² + 8 м² - 7424 м² = 82584 м².

3. 6 т 6 кг - 7 ц 3 кг: To subtract these quantities, we need to convert the centners (ц) to kilograms. We also need to make sure the units are aligned properly. Since 1 ton (т) is equal to 1000 kilograms, we can rewrite the expression as follows: (6 × 1000 кг + 6 кг) - (7 × 100 кг + 3 кг) = 6000 кг + 6 кг - 700 кг - 3 кг = 5703 кг.

4. 26 сут + 146 ч: To add these time periods, we need to convert them to a common unit. Since there are 24 hours in a day, we can convert 26 days to hours by multiplying it by 24: 26 сут × 24 ч + 146 ч = 624 ч + 146 ч = 770 ч.

Therefore, the final results are: 28560 kg + 78 ц 546 kg = 36906 kg 9 га 8 м² - 74 а 24 м² = 82584 м² 6 т 6 кг - 7 ц 3 кг = 5703 кг 26 сут + 146 ч = 770 ч
