For this case, we must make a rule of three, to find the percentage of the k-40 found in the sample found.
1.3 ----------> 100%
1 -------------> x
Where "x" represents the percentage of k-40 present in the sample found.
![x = \frac {1 * 100} {1.3}\\x = 76.9230](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B1%20%2A%20100%7D%20%7B1.3%7D%5C%5Cx%20%3D%2076.9230)
Rounding off we have:
76.92%

Answer:
76 14/20
(76 7/10) simplified
Step-by-step explanation:
First we make the denominator of the fraction equal
82 15/20
24 16/20
18 15/20
We then subtract
82 15/20 - 24 16/20
81 35/20 - 24 16/20 =
57 19/20
Then we add
57 19/20 + 18 15/20=
76 14/20
(76 7/10) simplified
