It is known that the image of inverse scale function y = 1 / X and y = 2 / X intersects the image of positive scale function y = 1 / 2 x at two points AB as shown in the figure, then OA ratio ob is equal to

It is known that the image of inverse scale function y = 1 / X and y = 2 / X intersects the image of positive scale function y = 1 / 2 x at two points AB as shown in the figure, then OA ratio ob is equal to

Y = 1 / X intersects with y = x / 2, and the focus is 1 / x = x / 2
The solution is x = radical 2, y = radical 2 / 2
So OA = (root 10) / 2
Y = 2 / X and y = x / 2 intersect, the focus is 2 / x = x / 2
The solution is x = 2, y = 1
OB = radical 5
So OA / ob = (radical 2) / 2
