Proportion Calculator (Cross Multiplication)
Proportion Calculator (Cross Multiplication): a planned Super Calculator tool. Stub page: the tool, its formula and a worked example are not published yet.
Proportion Calculator (Cross Multiplication) is a planned calculator in the mathematics section of Super Calculator, covering algebra and number theory.
What this calculator will compute
Inputs: three known terms, position of the unknown and proportion type (direct or inverse).
Outputs: missing term, constant of proportionality and cross multiplication steps.
Formula, recorded as scope and not yet verified against a primary source: Solve a/b = c/d for any missing term by cross multiplication: ad = bc. Direct proportion holds y = kx; inverse proportion holds xy = k, which changes the solution entirely.
