2. The atom fraction of $^{235}U$ in the uranium metal extracted on earth is 0.71%. Essentially, the remaining 99.29% is $^{238}U$. The half-life of $^{235}U$ is $7.03 \times 10^8$ years and that of $^{238}U$ is $4.468 \times 10^9$ years. Thus, long time ago in earth's history, the atom fractions were different from what they are now. Calculate the atom fraction of $^{235}U$ in the uranium that existed 2 billion years ago. (4 points)
