Third, calculation. (15× 0.5 = 8 points) Look out!
1 m -3 decimeter = 8 100 kg ÷ 9 = 9 10 g -2 10 g =
9 tons -4000 kg = 5044 g -3000 g = 8000 kg -5 tons =
1 km-10/0m = 2cm+48cm = 1 decimeter-9mm =
36 tons +60 tons = 100 km -85 km = 1 ton -400 kg =
9 kg 300 g -7 kg 200 g = 7 tons 40 kg-1 ton 20 kg =
63mm+17mm = () mm = () cm
