Final answer:
To compare and order the numbers 2.3, 28, 2.5, and 2 1/4, we can use a number line and locate each number between the whole numbers on the line.
Step-by-step explanation:
To compare and order the numbers 2.3, 28, 2.5, and 2 1/4, we can use a number line. Let's locate each number on the number line:
- 2.3: Locate 2.3 on the number line between the whole numbers 2 and 3.
- 28: Locate 28 on the number line between the whole numbers 27 and 29.
- 2.5: Locate 2.5 on the number line between the whole numbers 2 and 3.
- 2 1/4: Convert 2 1/4 to a decimal by dividing 1 by 4, which gives us 0.25. Locate 2.25 on the number line between the whole numbers 2 and 3.
Now, we can compare and order the numbers based on their positions on the number line. From smallest to largest, the order is: 2.3, 2 1/4 (2.25), 2.5, 28.
