Round for a reasonable estimate
Problem
Round \(48.672\) to the nearest tenth.
Big Picture
What this problem is really about
Rounding to the nearest tenth depends on two adjacent place values. We’ll identify the tenths digit, inspect the hundredths digit as the deciding digit, and use the five-or-more rule to decide whether the tenths digit stays or increases. Then we keep only the requested precision.
