Correct Answer

Given: Initial weight = 9 kg 750 g = 9,750 g Final weight = 3 kg 700 g = 3,700 g

Formula: Rice used = Initial weight - Final weight

Substitution: Rice used = 9,750 g - 3,700 g

Calculation: Rice used = 6,050 g 6,050 g = 6 kg 50 g

Answer: 6 kg 50 g of rice was used.

Explanation

The chapter explains subtraction of weights. Initial weight = 9 kg 750 g = 9,750 g. Final weight = 3 kg 700 g = 3,700 g. Rice used = 9,750 g - 3,700 g = 6,050 g = 6 kg 50 g.

Solution Steps

  1. Convert initial weight to grams: 9 kg 750 g = 9,750 g.

  2. Convert final weight to grams: 3 kg 700 g = 3,700 g.

  3. Subtract final weight from initial weight: 9,750 g - 3,700 g = 6,050 g.

  4. Convert the result back to mixed units: 6,050 g = 6 kg 50 g.
