To start, set up and equation using what you know.
(5/6) / (a/b) = (1/4)
Then, you need to isolate a/b. To do this multiply both sides by a/b and then divide by 1/4
5/6 = (a/b) (1/4)
(5/6) / (1/4) = (a/b)
Next, simplify the left side. To do this, take the inverse of 1/4 (which is 4) and multiply by 5/6 (this is also know as 'flip the second guy and multiply').
(5/6) • 4 = a/b
20/6 = a/b
Lastly, simplify to get the final answer.
10/3 = a/b

Answer : 64b^2 - 4
Hope that helps. If you need me to explain how I got my answer I will provide a picture.
The remainder is 5. To calculate this, first, divide 599 by 9 to get the largest multiple of 9 before 599. 5/9 < 1, so carry the 5 to the tens, 59/9 = 6 r 5, so carry the 5 to the digits. 59/9 = 6 r 5 again, so the largest multiple is 66. Multiply 66 by 9 to get 594, and subtract this from 599 to get 5, the remainder.
A=π(4)2=π·42≈<em>16pi ft^2</em>
