Answer:
using the same procedures as for numerical fractions
Step-by-step explanation:

Addition and subtraction, multiplication and division of rational expressions works exactly the same way as it does with numerical fractions. The notions of "least common denominator" and "cancelling common factors" (to reduce the fraction) also apply.
