Answer: Fractions equivalent to 1/2 are 2/4, 3/6, 4/8, 5/10, 6/12 ... Fractions equivalent to 1/3 are 2/6, 3/9, 4/12, 5/15, ... Fractions equivalent to 1/4 are 2/8, 3/12, 4/16, 5/20,
Using the formula
A = Pe^kt
Where A is the ending amount of population, P is the population k is a constant and 't' is time.
A = 0.39, t= 12 and p= 0.29
0.39= 0.29e^12k
1.34 = e^12k
ln1.34 = 12k
ln1.34/12 = k
K= 0.02
No the graph does not support his claim as k should be equal to 0.5

Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
