# Compare 40kg20g and 4020 g, 15t200kg and 1520 c, 8km7m and 870 dm, 90dm3sm and 9003 mm. help!

** Step-by-step explanation: **

__ of 1 kg = 1000 __

of 40 kg 20 g of gt; 4020 g

of 40 kg 20 g = 40*1000 + 20 = 40000 + 20 = 40020 g

of 40020 g of gt; 4020 g

__ of 1 t = 10 c __

__ of 1 c = 100 kg __

of 15 t 200 kg of lt; 1520 c

of 200 kg = 2 c

of 15*10 c + 2 c = 150 c + 2 c = 152 c

of 152 c of lt; 1520 c

__ of 1 km = 1000 m = 10000 dm __

__ of 1 m = 10 dm __

of 8 km 7 m of gt; 870 dm

of 8*10000 dm + 7*10 dm = 80000 dm + 70 dm = 80070 dm

of 80070 dm of gt; 870 dm

__ of 1 dm = 10 cm = 100 mm __

__ of 1 cm = 10 mm __

of 90 dm 3 cm of gt; 9003 mm

of 90*100 mm + 3*10 mm = 9000 mm + 30 mm = 9030 mm

of 9030 mm of gt; 9003 mm
