Final answer:
To compare the given expressions, we simplify each term and add them together to get the final result. The correct answer is option a, 0.63.
Step-by-step explanation:
To compare the given expressions, we need to simplify each of them and then compare the resulting values.
We have:
6x(1/10) + 3x(1/100) + 2x(1/1000)
Simplifying each term:
6x(1/10) = 6/10 = 0.6
3x(1/100) = 3/100 = 0.03
2x(1/1000) = 2/1000 = 0.002
Adding the simplified terms:
0.6 + 0.03 + 0.002 = 0.632
Therefore, the correct answer is 0.63 (option a).
