Like fractions, rational expressions can be
added, subtracted, multiplied, and divided,
When dealing with two rational expressions
that have different denominators, how would
you find a common denominator? What effect
would that have on the numerators of the
expressions? Would the same idea work for
simple numeric fractions? Why or why not?
Given two rational expressions, how would the
process you follow to multiply or divide them
differ from multiplying or dividing two numeric
fractions?
