Final answer:
Option C: 1.5 < 2.5 is the true inequality, as reflected on the number line, where 1.5 is to the left of 2.5 indicating it is less than 2.5.
Step-by-step explanation:
The student has asked which inequality is true and has mentioned the use of a number line to help determine the answer. After examining the inequalities and comparing their positions on the number line, we can determine which statement is accurate:
- Option A: -2.5 > -1.5 is false because -2.5 is to the left of -1.5 on the number line, meaning it is less than -1.5.
- Option B: -3 > -4.5 is true because -3 is to the right of -4.5 on the number line, meaning it is greater than -4.5.
- Option C: 1.5 < 2.5 is true because 1.5 is to the left of 2.5 on the number line, meaning it is less than 2.5.
- Option D: 3 < 0 is false because 3 is to the right of 0 on the number line, meaning it is greater than 0.
Using this information, we find that Option C: 1.5 < 2.5 is the true inequality.
