A basket containing 80 eggs weighs 2kg 300g. The same basket containing 60 eggs weighs 1kg 700g. Find the mass of the empty basket.

1 kg = 1000 g
2 kg 300 g = 1 kg + 1 kg + 300 g = 1 kg + 1000 g + 300 g = 1 kg 1300 g
2 kg 300 g  1 kg 700 g = 1 kg 1300 g  1 kg 700 g = 600 g
The mass of the empty basket = 600 g
