The U-Pb dating method relies on two separate decay chains, one of which is the uranium series from 238U to 206Pb with an apparent half-life of 4.47×109 years. A meteorite is thought to be 1.16×10^9 years old.

Calculate the theoretical mass ratio of 206Pb to 238U, 206Pb/238U, that should be observed when uranium-lead (U-Pb) dating is performed.
