Answer 1

1)36км765м
2)11км235м
3)6т750кг
4)4т545кг

Answer 2

1). 27км365м+9км400м=36км765м.

2). 18км455м-7км220м=11км235м.

3). 9т550кг-2т800кг=6т250кг.

4). 5т-455кг=4т545кг.

Answer 3

To solve these arithmetic expressions, we'll perform the operations step by step:

1. 27km 365m + 9km 400m: Convert everything to meters and then add: (27km * 1000m/km + 365m) + (9km * 1000m/km + 400m) = (27,000m + 365m) + (9,000m + 400m) = 27,365m + 9,400m = 36,765m

2. 18km 455m - 7km 220m: Convert everything to meters and then subtract: (18km * 1000m/km + 455m) - (7km * 1000m/km + 220m) = (18,000m + 455m) - (7,000m + 220m) = 18,455m - 7,220m = 11,235m

3. 9t 550kg - 2t 800kg: Convert everything to kilograms and then subtract: (9t * 1000kg/t + 550kg) - (2t * 1000kg/t + 800kg) = (9,000kg + 550kg) - (2,000kg + 800kg) = 9,550kg - 2,800kg = 6,750kg

4. 5t - 455kg: Convert everything to kilograms and then subtract: (5t * 1000kg/t) - 455kg = 5,000kg - 455kg = 4,545kg

So the results are:

1. 27km 365m + 9km 400m = 36,765 meters
2. 18km 455m - 7km 220m = 11,235 meters
3. 9t 550kg - 2t 800kg = 6,750 kilograms
4. 5t - 455kg = 4,545 kilograms
