    I am looking for a standard (would fit in the SSE) that deals with seeing the structure in a rational fraction to re-write, canceling out common factors (notice the avoidance of the word “simplify”).  Also one on adding unlike denominators in rational fractions.

    I would think it would fit nicely in a A-SSE 3d- so that is where I am looking.

    If there is not one that exists, can you tell me the rationale?

    I think I like the word “reduce” at least as much as “cancel” if not more, but there may be something I’m not considering.  I didn’t see “reduce” in the standards.

    The work with numerical fractions is intended to set the stage for algebraic fractions. Note the general formula for addition in 5.NF.1, and the reference to complex fractions in 7.RP.1.
