Explanation

The chapter explains subtraction of weights. Initial weight = 10 kg = 10,000 g. Sand used = 4 kg 500 g = 4,500 g. Sand left = 10,000 g - 4,500 g = 5,500 g = 5 kg 500 g. Alternatively: 10 kg - 4 kg 500 g = 10 kg - 4 kg - 500 g = 6 kg - 500 g = 5 kg 500 g.

Solution Steps

  1. Convert initial weight to grams: 10 kg = 10,000 g.

  2. Convert sand used to grams: 4 kg 500 g = 4,500 g.

  3. Subtract the used amount from the initial amount: 10,000 g - 4,500 g = 5,500 g.

  4. Convert the result back to kilograms and grams: 5,500 g = 5 kg 500 g.
