Best ResponseYou've already chosen the best response.1The half life of carbon 14 is 5700 years. So If a fossil is 5700 years old then half of the carbon14 is left. I think this may be it! I tried!

Best ResponseYou've already chosen the best response.3It's more of a chemistry question than math or biology. 1 half life: 100% > 50% 2nd half life: 50% > 25% 2 half lives.
