Answer: 
Explanation: 
We are asked to subtract 200 g from 1.61 kg. To perform this operation, we first convert kg to grams. 
Now, 
1 kg = 1000g 
therefore, 
1.61 kg = 1.61 * 1000 g = 1610 g.
The operation now becomes 
1610 g - 200 g 
 which evaluates to 
1610 g - 200 g = 1410 g 
Which is our answer!
