Worked Solution
Step 1: Identify the operation. Mei Hua HAD 4 2/3 kg and GAVE AWAY 1 1/3 kg, so we subtract: 4 2/3 − 1 1/3.
Step 2: Both fractions have the same denominator (3). Check if borrowing is needed: top fraction 2/3 is LARGER than bottom fraction 1/3, so no borrowing needed.
Step 3: Subtract whole numbers: 4 − 1 = 3.
Step 4: Subtract fractions: 2/3 − 1/3 = 1/3.
Step 5: Combine: 3 + 1/3 = 3 1/3. The fraction 1/3 is already in simplest form.
Final answer: 3 1/3 kg.
Answer: 3 1/3
Correct answer: 3 1/3
