Final answer:
To order the numbers from least to greatest, we compare decimal values, finding that 150.003 is the smallest, followed by 150.3, and then 153 is the largest.
Step-by-step explanation:
To order the numbers from least to greatest, we compare each number one by one, looking at the value of digits from left to right. Starting with the whole numbers, we see that 150 is the base for two of the numbers, and therefore we need to look at the decimal part to decide their order. We have:
When comparing, we see that 150.003 has less value after the decimal point than 150.3, making it the smallest of the two. Number 153 (B), being a whole number with no decimal places, is greater than both. Therefore, the order from least to greatest is:
- 150.003 (C)
- 150.3 (A)
- 153 (B)
