If xy=1, x/y=36, for positive numbers x and y, y=?
Choose the correct choice from the following
A) 1 / 2
B) 2
C) 1 / 3
D) 3
E) 1 / 6

Rationale: "very easy question . 2 variables and 2 easy equations . xy = 1 - - - > x = 1 / y - ( i ) x / y = 36 - - - > replacing ( i ) here - - - > 1 / ( y ^ 2 ) = 36 - - - > y ^ 2 = 1 / 36 - - - > y = 1 / 6 or - 1 / 6 the question states that x and y are positive integers . therefore , y = 1 / 6 is the answer . answer e ."
Answer: E
