Math helps with science because you'll need to know the math in order to convert units in science.
Answer:
64.5%
Step-by-step explanation:
Initial amount N° = ?
Remaining amount after decay = N = ?
k = decay constant = 0.00012 
t = time = 3650 year
fraction remaining will be N/N°
From the decay equation, N = N°
N/N° = 
N/N° = 
N/N° = 
N/N° = 0.645 = 64.5%
