Question

2800мм * 280дм 305067дм * 3км 5067дм 45900кг * 45ц 900кг 5000л * 50дм3

Answer 1

2800 мм < 280 дм  (1дм=100мм)                                                                        305067 дм > 3 км 5067 дм (1км=10000дм)                                                           45900 кг >  45 ц 900 кг (1ц=100кг)                                                                     5000 л >  50 дм³ (1л=1дм³)

Answer 2

To perform the calculations, I will convert all the measurements to the same unit system. Let's use meters as the base unit for length, kilograms as the base unit for weight, and liters as the base unit for volume.

1 decimeter (dm) = 0.1 meter (m) 1 centner (ц) = 100 kilograms (kg) 1 decimeter cubed (dm^3) = 0.001 cubic meters (m^3)

Therefore:

• 2800 mm = 2.8 m
• 280 dm = 28 m
• 305067 dm * 3 km = 30506.7 m * 3 km = 91,520,100 m
• 5067 dm * 45 ц = 506.7 m * 4500 kg = 2,280,150 kg
• 45900 kg = 45.9 metric tons (tonnes)
• 5000 L = 5 m^3
• 50 dm^3 = 0.05 m^3

Now, we can perform the calculations:

• 2.8 m * 28 m = 78.4 m^2
• 91,520,100 m / 45.9 t = 1,996.7 m/t
• 5 m^3 * 0.05 m^3 = 0.25 m^3

Therefore, the results are:

• The area of a rectangle with sides 2800 mm and 280 dm is 78.4 square meters.
• 305067 dm * 3 km is equal to 91,520,100 meters.
• 5067 dm * 45 ц is equal to 2,280,150 kilograms.
• 45900 kg is equal to 45.9 metric tons (tonnes).
• 5000 L is equal to 5 cubic meters.
• 50 dm^3 is equal to 0.25 cubic meters.
