- Building rational expressions
Observe the following examples; then try to speculate on the method.
To determine the quantity that the original denominator was multiplied by to yield the new denominator, we ask, "What did I multiply the original denominator by to get the new denominator?" We find this factor by dividing the original denominator into the new denominator.
It is precisely this quantity that we multiply the numerator by to build the rational expression.

The reason for building rational expressions
Building rational expressions
Normally, when we write a rational expression, we write it in reduced form. The reason for building rational expressions is to make addition and subtraction of rational expressions convenient (simpler).
