Refractive index of glass with respect to water is (9/8). Refractive index of glass with respect to air is (3/2). Find the refractive index of water with respect to air

Reflective index of glass with respect to air is 3/2. What is the refractive index of air with respect to glass ?

The refractive index of glass with respect to water is (9//8) . Refractive index of water with respect to air is (4//3) . Find refractive index of glass with air.

The reflective index of water with respect to air is 4//3 and the reflective index of glass with respect to air is 3//2 . Then the refractive index of water with respect to glass is

If the refractive index of glass with respect to air is (3)/(2) , what is the refractive index of air with respect to glass ?

If the refractive index of glass with respect to air is (3)/(2) , what is the refractive index of air with respect to glass ?

If the refractive index of glass with respect to air is frac(3)(2) then the refractive index of air with respect to glass___.
