Answer

3 kg 400 g\text{3 kg 400 g}

Step-by-step solution

3 steps
  1. Add the grams together.

    600 g+800 g=1400 g600 \text{ g} + 800 \text{ g} = 1400 \text{ g}
  2. Convert the total grams into kilograms and remaining grams.

    Recall that 1 kg=1000 g1 \text{ kg} = 1000 \text{ g}.

    1400 g=1000 g+400 g=1 kg 400 g1400 \text{ g} = 1000 \text{ g} + 400 \text{ g} = 1 \text{ kg } 400 \text{ g}
  3. Add this to the initial 2 kg2 \text{ kg}.

    2 kg+1 kg 400 g=3 kg 400 g2 \text{ kg} + 1 \text{ kg } 400 \text{ g} = 3 \text{ kg } 400 \text{ g}

    Therefore, 2 kg 600 g+800 g=3 kg 400 g2 \text{ kg } 600 \text{ g} + 800 \text{ g} = \boxed{\text{3 kg 400 g}}.
