Why 3/6 is not equivalent to 2/9

Because 3/6 equals 1/2 and 2/9 equals 1/3

3/6 simplified is 1/2. To compare the fractions, you multiply the fractions to get the least common multiple, which in this case is 18 (2 x 9 is 18.) I would multiply 1/2 times 9, which would be 9/18. I would then multiply 2/9 by 2 to get the bottom number to 18, which would be 4/18. You can see that 4/18 and 9/18 are not the same. This is why they are not equivalent.

Given that the half life of 3H is 12.3 years.

The amount of substance left of a radioactive substance with half life of t_{ \frac{1}{2} } after t years is given by

N(t)=N_0\left(\frac{1}{2} \right)^{ \frac{t}{t_{\frac{1}{2}} }

Therefore, the number of years it will take for 18% of the original tritinum to remain is given by

18 \% = 100 \% \left(\frac{1}{2} \right)^{ \frac{t}{12.3}} \\  \\ \Rightarrow\left(\frac{1}{2} \right)^{ \frac{t}{12.3}} =0.18 \\  \\ \Rightarrow\frac{t}{12.3}\ln\left(\frac{1}{2} \right)=\ln0.18 \\  \\ \Rightarrow\frac{t}{12.3}= \frac{\ln0.18}{\ln\left(\frac{1}{2} \right)} = \frac{-1.715}{-0.6931} =2.474\\ \\ \Rightarrow t=2.474(12.3)=30.4

Therefore, the number of <span>years that the time could be read at night is 30.4 years.</span>
