Answer:
2:5
Explanation:
The ratio can be found by turning both values into either grams or kilograms. For this, I will make them both into grams.
1. 800g is already in grams, so leave it.
2. 2kg is in kilograms, and 1 kilogram = 1000 grams.
3. 2 kilograms is equal to 2000 grams.
4. For this reason, 800g: 2000g can be simplified by making 800g into 2, and 200g into 5.
That is the ratio, 2:5
