Worked Solution
Step 1: Convert all masses to grams.
Total = 15 kg 350 g = 15 350 g
Parcel A = 2 kg 450 g = 2 450 g
Step 2: Find Parcel B.
Parcel B = 3 × 2 450 g = 7 350 g
Step 3: Find Parcel C.
Parcel C = Total − Parcel A − Parcel B
= 15 350 g − 2 450 g − 7 350 g
= 15 350 g − 9 800 g
= 5 550 g
Step 4: Convert back to kg and g.
5 550 g = 5 kg 550 g
Answer: 5 kg 550 g
Correct answer: 5 kg 550 g
