Answer:
Step-by-step explanation:
Given that 
is the repeating decimal.
The repeating decimal is converted into the fraction as
:
<=> 0.121212 = 
Multiplying both sides by x, we have,
<=> 0.121212x = 3
Dividing both sides by 0.121212, we get:
<=> x = 
<=> x = 25
So the fraction represents the decimal is:
Hope it well find you well.

Answer:
8.1 hours
Step-by-step explanation:
A model of the fraction remaining can be ...
f = (1/2)^(t/37) . . . . t in hours
So, for the fraction remaining being 86%, we can solve for t using ...
0.86 = 0.5^(t/37)
log(0.86) = (t/37)log(0.5)
t = 37·log(0.86)/log(0.5) ≈ 8.0509 ≈ 8.1 . . . hours
It takes about 8.1 hours to decay to 86% of the original concentration.
