I believe 30% is bigger than 
.
To find the answer, you'd have to convert both the fraction and the percent into decimal form to see which one is truly bigger. Converting the percent is fairly easy. 30% would become 0.30 is decimal form. To find the fraction in decimal form, you'd have to divide the numerator by the denominator, which would be 4 ÷ 15, which makes : 2.6666666666666666666666667.
Now you compare easily. Which one is bigger? 2.666666666666666666666667 or 0.30?
0.30 is bigger. So 30% is bigger out of both of them.

Answer: 693 years
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
k = rate constant
t = time taken for decomposition = 1
= Initial amount of the reactant
= amount of the reactant left =
for half life :
Putting in the values , we get
Thus half life of this isotope, to the nearest year is 693.
