Convert measurements within a system and use unit reasoning to choose the correct scale.
Put both measurements into the same unit
Problem
Rewrite \(2~\text{feet}\) and \(30~\text{inches}\) in the same unit, and compare the lengths.
Big Picture
What this problem is really about
Measurements with different units cannot be compared by their visible numbers alone. Pick one common unit, convert the other measurement with a conversion factor equal to one, and only then compare the numerical measures while tracking which original length produced each value. This prevents a correct conversion from being paired with a reversed conclusion.
