Final answer:
The set of decimal numbers correctly ordered from least to greatest is 308.463, 328.463, 330.693, 330.991. Numbers are compared digit by digit from left to right to determine the order.
Step-by-step explanation:
In order to order decimal numbers from least to greatest, you need to compare them digit by digit, starting from the leftmost digit. Let's compare the decimal numbers given in the options:
- 328.463
- 308.463
- 330.693
- 330.991
On comparing, we find:
- 308.463 is the smallest because it has the smallest hundred-digit ('3'), followed by zero tens which is less than 2 or 3 tens in other numbers.
- Next is 328.463 since it has '3' hundreds and '2' tens, which is smaller than '3' tens in the remaining numbers.
- Then we have 330.693 as it has a smaller decimal part ('693') compared to '991'.
- Finally, 330.991 is the largest number.
Therefore, the correct set of numbers in order from least to greatest is: 308.463, 328.463, 330.693, 330.991.
