23. Which number sequence is ordered largest to smallest?

Answer: C

Explanation:

3.0, 0.03, 0.003, 0.0003

The sequence 3.0, 0.03, 0.003, 0.0003 is ordered from largest to smallest. This arrangement accurately reflects the decreasing values of each number.

A) 0.0003, 0.003, 0.03, 3.0

This sequence is incorrect as it lists the numbers in ascending order, from the smallest (0.0003) to the largest (3.0). The values do not follow the required order from largest to smallest.

B) 0.03, 0.0003, 3.0, 0.003

This option also fails to provide the correct order. It incorrectly places 3.0, the largest number, towards the end of the sequence, which does not align with the largest to smallest requirement.

C) 3.0, 0.03, 0.003, 0.0003

This sequence correctly lists the numbers from largest to smallest. Each number decreases in value, making this the accurate choice for the question.

D) 3.0, 0.03, 0.0003, 0.003

While starting correctly with 3.0, this sequence incorrectly places 0.0003 after 0.03, which does not maintain the order from largest to smallest. Thus, it is not a valid option.

E) None of the above

This option is not correct, as option C provides a valid sequence that meets the criteria of being ordered from largest to smallest.

Conclusion

Option C is definitively correct because it accurately arranges the numbers in descending order of value. Other options fail to meet the criteria either by listing values in ascending order or by incorrectly positioning the numbers. Therefore, option C stands out as the only correct answer.
