Understanding the Problem
To convert the weight from kilograms and grams into a single unit (kilograms), we need to know the relationship between kilograms and grams.
- 1 kilogram (kg) = 1000 grams (g)
Breaking Down the Given Weight
The given weight is 2 kg and 57 g. We can convert it as follows:
- Convert grams to kilograms:
57 g can be converted to kilograms by dividing by 1000.
57 g = 57 / 1000 kg = 0.057 kg
- Add the two weights together:
Now, we can add the kilograms:
2 kg + 0.057 kg = 2.057 kg
Final Conversion
Thus, when you combine both the kilograms and the converted grams, the total weight is:
- Total weight = 2.057 kg
Selecting the Correct Answer
Now, let's look at the options provided:
a) 2.57 kg
b) 2.570 kg
c) 2.057 kg
d) None of these
From our calculations, the correct answer is:
- Option C: 2.057 kg
Conclusion
In summary, by converting grams to kilograms and then summing them, we arrive at the total weight of 2.057 kg, confirming that the correct choice is option C.
