1 billion is half of 2 billion.
Half of 6.5 billion is 3,250,000,000 (3.25 billion).
The sum of 16+2=18, and half of that is 9, so the question would be 16 minus what equals 9. So, the answer would be 7.

The half-life of Rubidium-87 is about 48.8 billion years. To determine the number of half-lives in 4.6 billion years, you divide the age of the Earth by the half-life of Rubidium-87: 4.6 billion years / 48.8 billion years ≈ 0.0943 half-lives. Thus, the age of the Earth represents approximately 0.09 half-lives of Rubidium-87.
