30cm/5dm = 3dm/5dm = 3/5
10 decimeters are in one meter, therefore 5dm is 0.5m.
First convert the different amounts into the same measuring system. In this case I choose the meter. 600cm = 6m 6km = 6000m 6000mm = .0006m 60m = 60m The biggest option is 6KM.
600cm are smaller.
6m =60dm=600cm=(600cm×10)=6000mm
1 cm is .01m so 600cm*.01m = 6m =] -ray
