If xy=1, x/y=36, for positive numbers x and y, y=?
If xy=1, x/y=36, for positive numbers x and y, y=?
Answer/Solution
1/6
Steps/Work
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.
