Order a proportion workflow

Order a reliable workflow for a proportional calculation.

Ratio direction map

Label both quantities before reducing to a per-one rate

  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.

Arrange in the correct order
  1. 1. Substitute and confirm the original ratio
  2. 2. Apply one consistent scale factor
  3. 3. Divide to calculate the per-one rate
  4. 4. Name both quantities, units, and requested direction
