Answer:
p(t) = 100%·2^(-t/1.32)
Step-by-step explanation:
The equation for exponential decay is ...
(remaining amount) = (initial amount)·2^(-t/(half-life))
Here, we can represent the percentage remaining by p(t) and the initial amount by 100%. Then, for a half-life of 1.32 minutes, the amount remaining is ...
p(t) = 100%·2^(-t/1.32) . . . . . where t is in minutes
_____
Alternate functional forms are possible, such as ...
p(t) = 100%·e^(-0.525112t)
p(t) = 100%·0.591489^t

Answer:
1/4
Step-by-step explanation:
Let the fraction be x/y
(x + 1)/y = 1/2
x/(y - 1) = 1/3 Cross multiply both equations.
====================
2*(x + 1) = y Remove the brackets
2x + 2 = y
################
3x = y - 1 Add 1 to both sides.
3x + 1=y - 1+ 1
3x + 1 = y
#################
Equate both ys
3x + 1 = 2x + 2 Subtract 1 from both sides.
3x + 1-1 = 2x + 2 -1
3x = 2x + 1 Subtract 2x from both sides.
3x-2x = 2x-2x +1 Simplify
x = 1
==================
y = 3x + 1
y = 3(1) + 1
y = 3 + 1
y = 4
The original fraction was 1/4
