A fraction of light refers to the portion of light that is transmitted, reflected, or absorbed when it encounters a surface or medium. This can be quantified mathematically as the ratio of the intensity of the transmitted or reflected light to the intensity of the incident light. Fractions of light are commonly used in physics and optics to describe how light interacts with different materials and surfaces.

There is no special name. The fraction of sunlight which is reflected will be different from the fraction of other light. The reflectivity of a surface varies with the wavelength of the incident light.
In general you cannot. A fraction is a pure ratio and does not have any distance associated with it. If it was a fraction of some measure of distance, the answer would depend on the units. A fraction of an inch would be a very tiny fraction of a mile while a fraction of a light year could be many miles.
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
Every fraction is an equivalent fraction: each fraction in decimal form has an equivalent rational fraction as well as an equivalent percentage fraction.
A fraction that has a different sign to the first fraction.
