B=1/2
9/16=1/2b(3/4)
Divide both sides by 3/4
1/4=1\2b
Multiply both sides by 2
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.

There is no fixed equation when I arrived at these numbers.
I just did trial and error. I came up with 25 and -8 as the numbers.
200 ÷ 25 = 8 ⇒ the sum of 17 depends on the signs of each numbers.
-8 x 25 = -200
-8 + 25 = 17
