To paint 2/5 of the wall in 1/2 hour, she can paint 1/2 * 5/2 = <<1/2*5/2=5/4>>5/4 of the wall in 1 hour.
To paint the whole wall, it will take her 1 / (5/4) = <<1/(5/4)=4/5>>4/5 hours. Answer: \boxed{4/5}.
To paint the whole wall, it will take her 1 / (5/4) = <<1/(5/4)=4/5>>4/5 hours. Answer: \boxed{4/5}.

Yes, the data table has a proportional relationship
No, the ratios are not equivalent
No, the table does not count consecutively
No, the ration 7:105 is not proportional to the other ratios.
First, let's find how much of the wall Zya can paint in 1 hour. Since she completes 2/5 of the wall in 1/2 hour, we can do the following calculation to find the amount she can paint in 1 hour:
(2/5) / (1/2) = (2/5) * (2/1) = 4/5
Hence, Zya can paint 4/5 of the wall in 1 hour.
Now, to find how long it will take Zya to paint 1/5 of the wall, we need to divide 1 hour by the amount she can paint in 1 hour:
1 hour / (4/5) = 1 hour * (5/4) = 5/4 hour
Therefore, it will take Zya 5/4 hour to paint 1/5 of the wall.
To find out how long it will take her to paint the whole wall, we multiply the time it takes her to paint 1/5 of the wall by 5:
(5/4 hour) * 5 = 25/4 hour = 6 1/4 hour
So, it will take Zya approximately 6 hours and 15 minutes (or 6.25 hours) to paint the whole wall.
