Report quantities with accuracy appropriate to measurement limitations.
Choose practical precision for a context
Problem
For a curtain-fabric order recorded as a length to the \(\text{nearest}~\text{inch}\), determine the appropriate precision from \(\text{nearest}~\text{inch}\), \(\text{nearest}~\text{mile}\), or \(\text{nearest}~\text{hundred}~\text{dollars}\). State the dimension match and how it meets the context requirement.
Big Picture
What this problem is really about
Practical precision has two filters: the reporting unit must measure the correct physical dimension, and its resolution must match what the task can actually use. A unit from the wrong dimension cannot report the quantity at all, while an overly coarse unit erases needed detail.
