Final Answer:
The correct order is: 3, √5, 1 x 10^(-2), 12% . None of the given options is answer.
Step-by-step explanation:
3 is the largest number.
√5 (approximately 2.236) is the second largest number.
12% (0.12) is the third largest number.
1 x 10^(-2) (0.01) is the smallest number.
Therefore, the list that correctly puts the numbers in descending order is:
3, √5, 1 x 10^(-2), 12%
None of the given options is answer.
