A ratio is the same as a fraction.
 
 
James          Nick              Ben       
______ =  ______   =   ______
 
  4                 3                 2
 
 
 
 
James          630              Ben       
______ =  ______   =   ______
 
  4                 3                 2
 
 
 
With this setup, we know that the ratio among the three people must be 210.
 
 
Let x = James' contribution
 
 
We set an equation.
 
x / 4 = 210
 
 
Solve for x to get James' contribution. 
 
x = 840
