Final answer:
The correct order from smallest to largest of the numbers 5.2, -5.5, and 3.0 is -5.5, 3.0, and 5.2.
Step-by-step explanation:
When ordering numbers, we arrange them from the smallest to the largest value. Negative numbers are always smaller than positive numbers, and among two positive numbers or two negative numbers, the one with the smaller absolute value is larger. Considering the numbers 5.2, -5.5, 3.0, the order from least to greatest would be -5.5, 3.0, and 5.2.
So the correct sequence is:
- -5.5
- 3.0
- 5.2
