Worked Solution
Step 1: Identify the operation. We want to find how many groups of 2/3 fit inside 6, which is a division: 6 ÷ 2/3.
Step 2: To divide by a fraction, MULTIPLY by its reciprocal (flip the fraction).
Reciprocal of 2/3 is 3/2.
6 ÷ 2/3 = 6 × 3/2.
Step 3: Compute.
6 × 3/2 = (6 × 3) ÷ 2 = 18 ÷ 2 = 9.
Check (reverse): 9 × 2/3 = 18/3 = 6 ✓
Final answer: Auntie Lim can paint 9 stools.
Answer: 9
Correct answer: 9
