A very, very tiny fraction of the two surfaces are eroded.
Multiply the numerator of one fraction to the other then multiply the denominator of one fraction to the other . Then reduce if possible.
A cube has six flat surfaces, but so do other solids. Look up 'hexahedron' in wikipedia.
A riddle is: I am a polyhedron I have two surfaces one of my surfaces is formed by a circle the other face is curved what am I?
All fractions are proportional to some other fraction.
If a fraction's numerator and denominator have no factors other than one in common, the fraction cannot be simplified except if the denominator is 1, in which case the fraction can be simplified to the whole number of the numerator.

Yes, rolling friction occurs when two solid surfaces slide over each other. This is true.
Not necessarily.
