Volumes can be transfered to liters only when their measurement units are dm³. a) Which means that: 0.45m³=450dm³ you move the decimal place three places to the right because m³ is larger measurement unit than dm³. 375 cm³ = 0.375 dm³; 75cl = 0.75l because of the prefix centi. 0.6dm³ = 0.6 dm³
So it will be 450l; 0.375l; 0.75l; 0.6l
b) 450l>0.75l>0.6l>0.375l
0.45m³>75cl>0.6dm³>375cm³
I hope i didn't make a mistake, but it would be good if somebody else answered too, so you can compare the answers and see if i made a mistake
