Sort the feature statements with the appropriate method:

Groups:

(a) Ratios & Proportions Method

,

(b) Dimensional Analysis Method

• Uses the “factor method” (aka the train tracks method”) multiplication & division to cancel unit

• Step by Step Procedure (can only see one step at a time)

• Uses Conversion factors to “cancel units”

• Uses conversion factors as ratios

• Fluid Procedure (can see all the steps at once!)

• Uses the cross multiplication method to solve for unknown x.

• The math starts with the given units

• The math shows an unknown “X”
