  1. LabelQuantity A compared with B
  2. DirectChoose the requested per-unit direction
  3. ReduceDivide both parts consistently
  4. ScaleApply one factor to both parts
  5. CheckUnits and cross-products agree

Direction determines meaning. Preserve the numerator and denominator units, scale both parts together, and substitute the result to check the relationship.
