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.

Friction occurs when two surfaces resist motion or slide against each other due to the contact between their irregularities at the atomic level, creating a force that opposes the direction of relative motion.
Friction. Friction is the force that opposes the motion of two surfaces sliding against each other. It occurs due to the interactions between the molecules on the surfaces of the objects.
When solid surfaces rub against each other, the type of friction that occurs is called dry friction or kinetic friction. It is generated by the contact between the surfaces and opposes the motion of the objects sliding past each other.
The friction that occurs when two surfaces slide past one another is called sliding friction. It is caused by the resistance between the molecules of the two surfaces as they interact and slide against each other. This frictional force opposes the motion of the two surfaces relative to each other.
When solid surfaces slide over each other, the friction is known as sliding friction. This type of friction occurs when two solid surfaces are in contact and slide against each other, resulting in resistance to the motion.
Static friction has the most resistance, as it occurs when two surfaces are not moving relative to each other. Kinetic friction has less resistance, as it occurs when two surfaces are sliding against each other. Rolling friction has even less resistance, as it occurs when a round object rolls over a surface.
The force that occurs when two objects rub against each other is called friction. Friction is a resistive force that opposes the motion of an object sliding against another object. It is caused by the interactions between the surfaces of the two objects.
Friction occurs when two material bodies in contact slide past one another.
This is called sliding friction, also known as kinetic friction. It occurs when two solid surfaces move or slide against each other.
The force that acts against objects sliding against each other is friction. Friction is the resistance that occurs when two surfaces come into contact and oppose the motion of each other. It acts in the opposite direction to the direction of motion.
