Final answer:
To order the numbers 5.8, 2.1, 8.22, 0.94, and 4.8 from least to greatest, look at the whole numbers followed by the decimal parts. The correct sequence is 0.94, 2.1, 4.8, 5.8, and 8.22.
Step-by-step explanation:
When ordering numbers from least to greatest, we compare each number's whole part and decimal parts in turn until we determine the sequence. Let's arrange the given numbers: 5.8, 2.1, 8.22, 0.94, and 4.8.
- 0.94: This has the smallest whole number part and is therefore the smallest number.
- 2.1: The next smallest whole number is 2, so this is the second number in our sequence.
- 4.8: Following the number 2, the next whole number is 4, placing 4.8 third.
- 5.8: This is just after 4.8 because it has the same whole number part but a larger decimal part.
- 8.22: This has the largest whole number part, making it the greatest number on the list.
Therefore, the numbers in order from least to greatest are: 0.94, 2.1, 4.8, 5.8, and 8.22.
