A lighthouse guide left decimal-coded markers along a foggy rocky coastline to help travelers find the safest path. Emek and Luna carried an important message that had to reach the lighthouse before nightfall. The markers showed the decimals 4.205, 4.250, 4.025, 4.520, and 4.252, but they had been mixed up by the wind. By carefully comparing the ones, tenths, hundredths, and thousandths places, Emek and Luna arranged the markers from least to greatest. The correct order revealed the safe route, and they reached the lighthouse in time to deliver the message.
