Hint: To solve this question we will use the formula of conversion of grams into kilograms that is kg which is given as 1kg = 1000 grams. We will separately solve both the given parts (i) and (ii) to get the required result.

Complete step-by-step answer:
Let us consider part (I).
(I) 200g
We have to convert 200g into kilograms (kg). We have a conversion formula for converting kilograms (kg) into grams (g) which are given as 1 kg = 1000g. Now, as we need to convert grams (g) into kilograms (kg) and not kilograms (kg) into grams, so we will calculate the formula of the other side by using
1kg=1000g
1000g=1kg
Dividing both the sides of the above equation by 1000, we have,
1000g1000=11000kg
1g=0.001kg.....(i)
Hence, finally, we have the conversion formula of g into kg. Let us use this formula stated in the equation to solve our question. We have 200g = ? kg. As, 1g = 0.001 kg, using equation (i), then by applying the unitary method, we have,
200g=200×0.001kg
200g=0.200kg
200g=0.2kg
Hence, 200g is nothing but 0.2 kg.
200g=0.2kg
Let us similarly solve part (II)
(II) 3470 g
Let us solve this by using equation (i).
1g=0.001kg
Using the unitary method, we have,
3470g=0.001×3470kg
3470g=3.470kg
Therefore, 3470g is nothing but 3.470 kg.
Hence, we have obtained our answers.

Note: A key point to note here in this question is that while calculating 200g and writing it as 200g = 0.2 kg, we have removed 2 zeroes after 0.2, this is so because ‘0’ to right-hand side of the decimal doesn’t matter. Also, note that 3.470 remains as 3.470 kg.
