Adding
Add two numerical fractions that share the denominator , then simplify the result by factoring out common factors:
Step 1 — Add the numerators over the common denominator. Since both fractions already share the denominator , combine the numerators directly:
Step 2 — Factor the numerator and denominator to reveal common factors. Write and :
Step 3 — Divide out the common factor. Cancel the shared factor of from the numerator and denominator:
This numerical example previews the same three-step procedure used for adding rational expressions with a common denominator: combine the numerators, factor completely, and simplify by removing common factors. The only difference when working with rational expressions is that the numerators and denominators are polynomials rather than plain numbers.

In a corporate logistics database, when combining two efficiency formulas that share a common denominator, what is the required step after adding the numerators to ensure the resulting expression is fully simplified?
In a professional data report, when a marketing analyst subtracts one rational expression from another that shares the same denominator, the denominator of the resulting expression is found by subtracting the second denominator from the first.
A technical specialist is documenting the standard operating procedure (SOP) for combining algebraic performance metrics (ratios) that share a common denominator. Match each stage of the 3-step procedure to the correct action required to ensure the final formula is accurate and simplified.
Procedural Steps for Combining Efficiency Formulas
In a professional data analysis report, when an analyst adds or subtracts rational expressions that share a common denominator, they first combine the numerators. According to the standard 3-step procedure, the analyst must then ____ both the numerator and the denominator completely to identify any shared factors that can be simplified.
