Worked Solution

Step 1: Identify the digit in the tenths place. 3.67 → tenths digit is 6. Step 2: Look at the digit in the hundredths place to decide whether to round up or keep the same. Hundredths digit = 7. Since 7 ≥ 5, round the tenths digit up. 6 + 1 = 7 Step 3: Write the answer. 3.67 rounded to 1 decimal place = 3.7

Correct answer: 3.7
