The ratio of the isotopes carbon-14 (14C, radioactive and decaying) to carbon-12 (12C non-radioactive and non-decaying) is an important indicator to determine age of fossils, woods and other organic remnants of plants and animals. Assume an animal skeleton was found with a ration 14C/12C of 61% and a half-life h of 14C of 5730 years
