1/2 never - 03 Dec '04 16:52 / 1 edit

NO..not exactly. Gambitzoid's solution needs only slight correction as follows.*Originally posted by red king richie128***that was easy right**

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. - 03 Dec '04 17:19

That goes to show that even 8 th grade mathematics should not be taken for granted.*Originally posted by howzzat***NO..not exactly. Gambitzoid's solution needs only slight correction as follows.**

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:'(*Originally posted by Dodger11***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.** - 07 Dec '04 10:29

if it sucks... lets make it more interesting...*Originally posted by Dodger11***Oooops....a portion of the entire cake, not their respective portions..my bad.Oh well, the puzzle sucks anyway.**

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? - 09 Dec '04 22:37

It's been a while since I've done calculus, so I could be wrong, but I've calculated the answer to be 6.*Originally posted by Gambitzoid***if it sucks... lets make it more interesting...**
