Worked Solution

Step 1: Identify the tenths digit. In 2.485, the tenths digit is 4 (the first digit after the point). Step 2: Look at the digit immediately to the right (the hundredths digit). It is 8. Step 3: Since 8 ≥ 5, round UP: the tenths digit goes from 4 to 5. Step 4: Drop the rest. Final answer: 2.5 m. Answer: 2.5 m

Correct answer: 2.5 m
