Worked Solution
Step 1: Convert both mixed numbers to improper fractions.
4 1/2 = (4 × 2 + 1) / 2 = 9/2
1 3/4 = (1 × 4 + 3) / 4 = 7/4
Step 2: Find the lowest common denominator (LCD) of 2 and 4.
LCD = 4
9/2 = 18/4
Step 3: Subtract the fractions.
18/4 − 7/4 = 11/4
Step 4: Convert back to a mixed number.
11 ÷ 4 = 2 remainder 3
11/4 = 2 3/4
Final answer: 2 3/4 kg
Answer: 2 3/4 kg
Correct answer: 2 3/4 kg
