Worked Solution
Step 1: Convert the total mass to grams.
1 kg = 1000 g
5 kg 300 g = (5 × 1000) + 300 = 5000 + 300 = 5300 g
Step 2: Convert the removed mass to grams.
2 kg 100 g = (2 × 1000) + 100 = 2000 + 100 = 2100 g
Step 3: Subtract to find the remaining mass.
5300 g − 2100 g = 3200 g
Answer: The remaining sand has a mass of 3200 g.
Correct answer: 3200 g
