There are 1000g in 1kg, therefore, there are 4000g in 4kg.
800/4000 = 8/40, which can be simplified to 1/5.
800g is 1/5 (one fifth) as much as 4kg.
8 kg = 8,000g 800g is less than that.
800/1,000 = 8/10 = 4/5
8/10 or 800g/1000g
8kg is bigger than 800g
The answer is clearly 4/5
1 kilogram = 1000 grams fraction = 400 / 1000 = 40 / 100 = 4 / 10 = 2 / 5 So 400 grams is two fifths of 1 kilogram
(.8kg)(1000g/kg)=800g
800 g is 0.8 kg.
It is 72p.
4 Kg Obviously.
It is: 3/4
Please be precise in your questions! If you mean what fraction of 1 kg is 0.4 kg then it's 2/5 or 20%
