The quantity that helps determine the absolute age of rocks and fossils is **the ratio of carbon-12 to carbon-14**. Carbon-14 dating is a common method used to date organic materials based on the radioactive decay of carbon-14, and it requires measuring the ratio of carbon-12 (a stable isotope) to carbon-14 (a radioactive isotope).
