Cells are limited in size by their surface area and volume ratio which means that when cells get so large, there is a limit that they can no longer obtain enough oxygen and nutrients. This process is involved in cell growth. 
        
             
        
        
        
The given information is expressed in ratio. However, a ratio is basically a fraction. So, 4:10 is just equal to 4/10 or 2/5 in simplified terms. Similarly, 12:20 is just equal to 12/20 or 6/5 in simplified terms. The smaller ratio is 2/5 because the numerator is less than the denominator. So, it follows that the answer is less than 1. The other ratio has a much greater numerator. So, we would expect that that would be greater than 1.
