| Do the fractions have to be exact, or can they be rounded off?
My guess is the same as Rich's 6,3 and 2.
If the fractions have to be exact, you could figure which components of the cars are not critical to the function of the cars and remove those parts until you reach the exact number. Things like hub-caps, radios... Of course you also have to decide what criteria you are going to use to determine how you are going to divide it up, by weight, cost of item... |
