this kid was six years old and his dad was thirty. his dad said how about we split our birthday cakes according to our age? i get 30 slices and you get six. how old will the kid be when he gets 1/4 of the cake 1/3 and 1/2? this is basic 8th grade proportions and should be pretty easy

NO..not exactly. Gambitzoid's solution needs only slight correction as follows.
1/4 at 12 years..
1/3 at 24 years...
1/2 never.....
This is on account of the fact that there has to be a constant difference of 24 years in the age of father and his son in the given puzzle.

That goes to show that even 8 th grade mathematics should not be taken for granted.

Am I missing something????? After 18 years, the 6 year old will be 24, and the father will be 48...THAT IS HALF!!! THAT IS HALF!!!! THAT....IS....HALF....Jebus, what kind of puzzlers are you? Maybe you SHOULD go back to the 8th grade, durhhhhhhhh.

hey you idiot when he is 24 his dad is 48. 48 plus 24 equals 72. so he gets 24 out of 72 that is not half. huhhhh sad:'(

if it sucks... lets make it more interesting...

at what age does the instantaneous rate of change of the fraction of cake he recieves equal 1/54 piece of a cake per year?

It's been a while since I've done calculus, so I could be wrong, but I've calculated the answer to be 6.
