Answer: Not proportional

=======================================================

Step-by-step explanation:

Let's assume the two fractions are equal.

If so, then,


(0.2)/(2.6) = (0.3)/(3.6)\\\\0.2*3.6 = 2.6*0.3\\\\0.72 = 0.78

The last equation is false, so the first equation is false.

Therefore, the two ratios are not proportional.

-------------

Another approach:

Calculate the decimal value of each fraction


(0.2)/(2.6) \approx 0.07692\\\\(0.3)/(3.6) \approx 0.08333\\\\

The two ratios result in different decimal values, so the two ratios are not equal, aka not proportional.
