Square root of 5 is about 2.24
5/2 is 2.5
2.71 is 2.71
2 3/4 is 2.75
2.24, 2.5, 2.71, 2.75

Day 1: 1200g / 2¹ = 600g
Day 2: 1200g / 2² = 300g
Day 3: 1200g / 2³ = 150g
The pattern is the amount of radioactive substance on day n is 1200 / (2^n).
Therefore, we have to find n where 2^n > 1200.
The first such n is 11 (2¹¹ = 2048).
Hence, there will be less than 1 gram on day 11.
