Find the ratio of weights of 1 gram of cotton to 1.5 gram of rubber if their densities are in the ratio of 1 : 2.

• This is a very simple question. Since the ratio of weights is the question, one need not care about their densities.
  
  Hence 1 gram of cotton : 1.5 gram of rubber will be in the ratio 1/1.5 = 2/3 (as simple as that :))
