Four race times are 9.8, 9.75, 9.805 and 9.79 seconds. Which list orders them from fastest to slowest?

Explicación

A faster time is smaller, and alignment gives 9.750 < 9.790 < 9.800 < 9.805. Putting 9.8 first because it has fewer written digits reverses the numerical comparison rather than ordering the times.
