Worked Solution
Step 1: Convert each distance to sixths (LCD of 3, 6, and 2 is 6).
2⅓ = 14/6, 1⅚ = 11/6, 3½ = 21/6
Step 2: Add the three distances.
14/6 + 11/6 + 21/6 = 46/6 = 23/3 km
Step 3: Divide equally over 4 days.
23/3 ÷ 4 = 23/3 × 1/4 = 23/12
Step 4: Convert to a mixed number.
23/12 = 1 11/12 km
Answer: 1 11/12 km
Correct answer: 1 11/12 km
