You first want to convert all to the same unit, so lets convert them to grams
30g= 30g
3000cg = (3000cg/100)= 30g
30dg= (30dg/10)=3g
0.30kg= (0.30kg*1000)=300g
So 30dg contains the smallest amount of matter

Well, Moorelyssa, the answer to that question is:30 g = 0.03 kg 
3000 cg = 30g = 0.03 kg 
30dg = 300g = 0.3 kg 
0.3kg = 0.3 kg 
Answer is 30g and 3000cg have the least matter.
